Description

one

This invention relates to explosive electrical annaparaMi, in particular, to trip switches and push-button control stations.

Izvstnyyelektricheskie apparatus, comprising a housing, driving and input devices, switching and input camera, formed by a housing, lids in an explosion-proof partition, the side walls of which are the side walls of the housing, pass-through clamps are fixed on the explosion-proof partition, connected through current leads to the fixed switching contacts; on one side there are partitions and having terminals for fastening the conductors introduced into the apparatus with a spring. The complexity of the design of the apparatus leads to an increase in its dimensions, mass, cost.

Also known are explosion-proof electrical devices, comprising a housing, a device and an input device, switching and input devices formed by a housing, a lid and a explosion-proof partition, the side walls of which are in-

The side walls of the casing are mounted on the explosion-proof partition, pass-through clamps with fixed fixed contacts on one side of the diffuser and fastening terminals of the conductors inserted into the apparatus on the other are fixed.

These devices are most relevant to the invention in terms of technical nature and the result achieved.

The need to remove an explosion-proof partition of the apparatus for fastening the conductors inserted into the apparatus to the terminals of the conductors and the lack of visual integrity monitoring: installation after installation of the partition into the apparatus complicates operation.

The aim of the invention is to reduce the size and simplify the operation of the apparatus.

It is achieved by the fact that an explosion-proof electric apparatus, comprising a housing, a driving and input device, switching and introductory chambers, formed by a housing, a cover and a blast

A permeable partition, the side walls of which are the side walls of the housing, on the explosion-proof partition there are fixed passage clamps with fixed contacts on one side of the partition and terminals. for fastening the conductors inserted into the apparatus on the other, it is equipped with an additional cover, the drive device is placed in one of the side walls of the explosion-proof partition, and the other one contains the Bvoanoy device, while the introductory measure is closed by an additional cover}

located parallel to the explosion-proof wall at the location {) of the location of the terminals.

The drawing shows an explosion-proof electrical apparatus in section.

The explosion-proof electrical apparatus comprises an I case 1, / a driving device 2 and an input device formed by a nut 3 and a sealing ring 4, a switching chamber 5 and a second / six camera;

The chambers 5 and 6 are formed by the housing 1, the lid 7 and the flameproof partition 8, the side walls 9 in which South are the side walls of the housing 1.

On the ryvonepronidable partition 8, passages are secured in clamps 11 about by crimping 12, which are mounted on their own nipples 12, on one side, partitioning .8 and terminals 13 for fastening injected ia - devices of conductors 14. with another.

In the side wall 9, the projectile of my septum is placed in the drive unit 2, and in the side wall 10 is an insertion device.

The input chamber 6 is closed by an additional lid 15, which is parallel to the gap between the impermeable walls and the partition 8 and the location of the terminals 13.

When placing the drive and input devices in the side walls of the explosion-proof. The partitions reduce the size of the device, its mass and cost, and when using an additional cover that covers the inlet chamber and is located. Parallel to the flameproof partition at the location of the terminals, simplifies the operation of the device, its mounting.
