    The invention relates to electrical equipment, to electrical distribution devices in explosion-proof design with a main bus and an input side, controlling priors in pressure resistant corus, between which explosion-proof contact elements are located.
    The aim of the invention is to simplify the design.
    FIG. 1 shows a section of a main busbar with two pressure-resistant housings attached to it and one body separated from it; in fig. 2 - the main tire in the section and the switching device in a pressure-resistant case, collection type.
    Shown in FIG. The 1 section of the main busbar 1 of the explosion-proof switchgear 2 has a housing 3 with a rectangular cross section in which three conductors of the busbar 4 are placed one above the other, isolated from each other (FIG. 2). The main busbar channel can be locked with the help of a special connecting body for supplying the power cable. If the power supply to the main busbar conductors 4 is otherwise supplied, there can be a locking lid. The main busbar 1 is made in a spark-proof casing 3, in which explosive sparks should not occur, Spark-blistering (the casing 3 can therefore be made in comparison with pressure-resistant housings relatively light. For mounting the casing 3. fixing parts are provided corners 5. The main busbar case 3 of the main busbar i can be mounted on the frame or on the stand. The protruding frame 6 serves to introduce the pressure-resistant case 7.
    Switching devices belonging to switchgear 2 are housed in several pressure-resistant housings 7. Two such housings 7 are shown in the position they occupy during operation and in which they are mounted on the main busbar 1. The next pressure-resistant casing 7 is shown in the above position in order to show the interaction of the part of the plug-in connector 8, which is connected from the socket 9, located on the front side 10 of the housing 3 and the plug-in part 11, which is located on the front surface STI 10 of the pressure-resistant housing 7. In the illustrated example, plugs of compound 8 vsholneny three-pole, i.e. in the socket 9 and the plug part 11, respectively, the contact elements corresponding to the phases of the three-phase current system and the protective conductor contact are combined. Additionally, the socket 9 and the plug part 1 may contain additional contact elements for control circuits. In addition, plug-in connections can be made as connections of 5 single contacts. The plug-in connection closes the control circuit of the switching devices or the safety switch located in front of the main busbar at the yci-anovka pressure-resistant housing
    7 to the main busbar 1 only when the high current plug connection 8 which consists of the socket 9 and the plug part 11 is reliably closed. In the present example, however, a special limit switch 12 is provided, mechanically actuated when pressure resistant housing 7 is connected to the main busbar 1 (Fig. 2).
    Each of the pressure-resistant enclosures 7 is equipped with four screws 13 located in the corners of the housing 7. The screws 13 interact with the corresponding threaded bushings 14 located on the front side 10 of the main busbar 1. The length and installation of at least one of the screws 13 are selected such that, in any case, a mechanically perceptible connection is created before the contact elements of the high-current plug-in contact come in contact with each other. So the screw closest to the plug-in part 11 is made. Their proximity ensures that the insertion forces are created practically only by this screw, while the rest of the screws serve only for fastening.
    In this case, the plug connection 8 is made explosion-proof so that it forms an explosion-proof volume before the contact elements touch each other. If, when a pressure-resistant housing 7 is installed on the main busbar 1, an explosive mixture is formed, its breakdown is prevented, since plug-in connection 8 already forms an explosion-proof volume and disconnects this plug-in connection and accordingly opens the pressure-resistant plug-in space. This is eliminated due to the mechanical connection already created by the screws 13.
    Instead of the frame 6 for supporting the pressure-resistant case 7, other devices can also be provided, for example in the form of incoming tires, which, moving away from the front side 10 of the main busbar, extend forward.
    The explosion-proof switchgear can be made with protective clamps 15, which are provided with each socket 9 plug connections. The protective covers 15 are hinged respectively under the socket 9 on the front side 10 of the housing 3 of the main busbar I and, under the action of their own weight, occupy the position shown in FIG. 1 in the area of the first panel to the left of the main busbar I. If the switchgear 2 is to be operated when one or several housings 7 are missing, the free sockets 9 are closed by tilting up the protective clamps 15 and fixed in this position with a screw 16. This the screw passes through the corresponding hole; the cover 15 and in the same way enters the left upper threaded bushing 14 as the corresponding screw 13 of one of the housings 7. This also activates the limit switch 12 and the device becomes ready for operation. The protective cap 15 in the working position is shown on the second panel on the left in FIG. one.
    The device also contains a control circuit 17 (Fig. 2).
    In an embodiment of the device according to FIG. 1 The dimensions of the main busbar 1 are made for four equally sized enclosures 7. A switchgear of this kind can be expanded due to the fact that the same main busbar is mounted on the imaged main busbar 1 and connected to it in such a way that it can then be used accordingly more pressure resistant housings 7; In addition, main busbars can be used for more or less pressure resistant housings in the same way as other sized housings 7.
