All the outlet surfaces available for touch when the socket is installed, as under normal use, test the above device. Takenks, which are a non-removable part or intended to be embedded in the device are tested in a position, as in normal use. Takenks intended for fastening on the device, Mounted on a vertically located sheet of plywood with a thickness of 8 mm and sizes of 175175 mm without any metal gasket from the back of the sheet. Fan is fixed on a rigid frame, which is installed directly on the hard base, for example, from bricks, reinforced concrete, etc. Avents are applied by All surfaces available for touch. The testing device is calibrated on the impact energy of the pendulum depicted in Figures 17-20 GOST 30988.1. According to each test plane, it is applied three strikes into each of the three weaker points (no more than nine blows). Tablik 103.

It is necessary to ensure that the results of one series of three strikes do not affect the results of the following series of shocks. If there is a doubt that the reason for the socket is the previous series of shots, then this defect is neglecting a series of three blows that caused defects, apply along the same place on A new sample, which should withstand this test. Before the tests should not be damaged samples that violate the requirements of this standard. There should not be open to the current parts. The device consists of three main parts: the hull, shock element and a trigger cone with a spring. Curpose consists of a casing of the guide of the shock element, a trigger and other parts that are rigidly attached to it. The mass of the housing should be (1250 ± 10). Prospect - do not take into account: - damaged edges, small potholes that do not reduce the leakage paths or air gaps below the values \u200b\u200bspecified in 26.1; - small chips that do not affect defeat protection electric shock, or water ingress; - cracks that are not visible to the naked eye, and surface cracks of fibrous castings and similar parts; - cracks or holes on the outer surface of any part of the socket, if the socket meets the requirements of this standard, even without this part. The element consists of a hammer head, a rod and a platoon buttons. The weight of the impactor should be (250 ± 1). The hammer head has a semicircular form with a radius of 10 mm and is made of a polyamide with a hardness of 100 HRC; It must be attached to the hammer rod so that the distance between its vertex and the plane passing through the cone ends immediately before the shock element is equal to 20 mm. The cone is equal to 60 g, the cone spring itself immediately before the shock element should create an effort 20 n Flag of the shock element is adjusted so that the product of compression magnitudes in millimeters for power in Newtona equals 1000, and its length in compression was about 25 mm. With such an adjustment, the impact energy must be equal to (0.5 ± 0.05) J. Springs of the trigger must be adjusted so that the pressure generated by them was enough to hold the clips of the trigger mechanism in the selection state. It should not exceed 10 N. Configuration of the rod, the hammer heads and the device adjustment devices of the hammer should be such that the hammer spring is released all the stored energy for 1 mm before applying the peak of the hammer head of the impact. In the last millimeter of movement before the blow, the shock element should, besides friction, to be a freely moving mass, having only kinetic energy. Device is administered by pulling out the removal handle until the trigger clamps are engaged in engaging with the gods of the hammer rod. By pressing the trigger cone to the sample in the direction perpendicular to the surface at a point being subjected to the test. The pressure is gradually increased so that the cone moves back until it contested the rods of the trigger, which when moving back, drive the trigger and will allow the hammer Apply a blow. The form in the assembled form is rigidly attached to a flat surface and apply three blows into each point of the housing, which seems weak in mechanical strength.

Planning the placement of electrical wiring in the room is a serious task, on the accuracy and correctness of which the quality of subsequent installation and the level of safety of people in this area depend on it. In order for the wiring to be placed efficiently and competently, it is required to pre-make a detailed plan.

It is a drawing performed in compliance with the selected scale, in accordance with the layout of housing, reflecting the location of all electrical wiring sites and its main elements, such as distribution groups and a unicinerary schematic diagram. Only after the drawing is drawn up, you can talk about connecting the electrician.

However, it is important not only to have such a drawing at the disposal, we must also be able to read it. Each person who is dealing with the works involving the need for electrical installation should be guided in the conventional images in the diagram denoting various elements of electrical equipment. They have the form of certain characters and contains almost every electrical circuit.

But today it will be not talking about how to draw the plan scheme, but about what is displayed on it. I will say immediately complex elements, such as resistors, machine guns, switches, switches, relays, engines, etc. We will not consider it, and consider only those elements that meet any person every day i. Designation of sockets and switches in the drawings. I think it will be interesting to everyone.

According to what documents the designation is regulated

Designed in Soviet times, the GUTO clearly define compliance with the circuit and in the design documentation of the electrical chain elements with defined set graphic symbols. This is necessary to maintain generally accepted records containing information about the design of the electrical system.

The role of graphic designations is performed by elementary geometric shapes: squares, circles, rectangles, points and lines. In a variety of standard combinations, these elements reflect all components of the electrical appliances, machines and mechanisms used in modern electrical engineering, as well as the principles of management of them.

Often there is a natural question about the regulatory document governing all the above principles. Methods for constructing conditional graphics images of electrical wiring and equipment on the respective schemes determines GOST 21.614-88 "Images Conditional graphics electrical equipment and places on the plans". From it you can find out as designated sockets and switches on electrical circuits.

Designation of sockets in the scheme

Regulatory technical documentation gives a specific outlet designation on electrical circuits. Its common schematic species is a semicircle, from the convex part of which the draw is the draw, its appearance and determines the type of socket. One trait is a two-pole socket, two - dual biplar, three, having a view of a fuel, is a three-pole socket.

Such sockets are characterized by the degree of protection in the IP20 - IP23 range. The presence of grounding is indicated in the schemes of a flat feature parallel to the center of half of the circle, which distinguishes the designation of all open settings.

In the event that the installation is hidden, schematic images of sockets are changed by adding another feature in the central part of the semicircle. It has directions from the center to the drawing, indicating the number of poles of the outlet.

The sockets themselves are inserted into the wall, the level of their protection against moisture and dust is in the range above (IP20 - IP23). The wall does not become dangerous from it, since all parts conducting the current are reliably hidden in it.

Some patterns of the designation of sockets have a kind of black semicircle. This is moisture-proof outlets, the degree of protection of the shell of which IP 44 - IP55. Their external installation is allowed on the surfaces of buildings overlooking the street. In residential premises such sockets are installed in wet and rawrooms, such as bathrooms and showers.

Designation of switches on electrical circuits

All types of switches have a schematic image in the form of a circle with a feature at the top. Circle with a dishes containing a hook on the end, indicates a classroom open installation lighting switch (Degree of protection IP20 - IP23). Two hooks at the end of the dummy means a two-block switch, three - three-key.

If the perpendicular line is put on the schematic designation of the switch above the screenshot switch hidden installation (Degree of protection IP20 - IP23). The line is one - a single-pole switch, two - two-pole, three - three-pole.

The black-in-color circle is indicated by a moisture-proof opening switch (IP44 - IP55 protection degree).

The circle intersected by the shells line at the ends is used for the image on the electrical circuits of the passing switches (switches) with two positions (IP20 - IP23). The image of a single-pole switch resembles a mirror image of two ordinary. Moisture-resistant switches (IP44 - IP55) are designated in diagrams in the form of a painted circle.

As designated block switches with a power outlet

To save space and for the purpose of layout in the total block, install a socket with a switch or several sockets and a switch. Probably, many such blocks met. This placement of switching devices is very convenient, since it is in one place, moreover, when installing wiring can be saved on the strokes (wires on the switch and sockets are packed in one stroke).

In general, the layout of blocks can be anyone and everything as they say depends on your imagination. You can set the switches block with a socket, multiple switches or multiple sockets. In this article, do not consider in such blocks I just have no right.

So, the first of them block socket switch. Designation for hidden installation.

The second is more complicated, the block consists of a single-wave switch, a two-block switch and a grounding socket.

The last designation of sockets and switches in electrical circuits is displayed as a block of two switches and a socket.

For clarity, only one small example is presented, you can collect (draw) any combination. Once again, it all depends on your imagination).
