Description
Technical Field
The utility model relates to an explosion-proof machine terminal box, concretely relates to main power source terminal box that area malleation was swept.
Background
At present, high-voltage explosion-proof motors at home and abroad mainly comprise three types, namely an explosion-proof type, an increased safety type and a positive pressure shell type. Because the shell of the explosion-proof motor is special, the single-machine power and the volume are limited, the large-scale equipment driving needs to use two explosion-proof motors of an increased safety type or a positive pressure shell type, but the increased safety type motor can only be used in the environment that danger is divided into two areas, so that the positive pressure shell type motor is more widely applied. However, the traditional positive pressure shell type motor main body adopts a positive pressure structure, and the junction box adopts an increased safety type junction box, so that the application safety performance in an explosion-proof occasion is not high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, and provide a main power source terminal box that area malleation was swept.
The utility model discloses a solve the technical scheme that above-mentioned technical problem took and be:
the utility model provides a take main power source terminal box that malleation was swept includes that wiring casing, wiring board, terminal, glan head, malleation sweep device and relief valve, and the built-in wiring board of wiring casing is equipped with the terminal on the wiring board, is equipped with the glan head on the wiring casing, and the malleation sweeps the device and passes through intake pipe and wiring casing intercommunication, is equipped with the relief valve on the wiring casing, and the manometer setting on the malleation sweeps the device is on the wiring casing.
Compared with the prior art, the utility model following beneficial effect has:
the utility model discloses a sweep the device through the malleation and let in non-combustible gas in the wiring casing to detect wiring casing internal pressure through the manometer, make wiring casing internal pressure remain stable, and make wiring casing internal pressure be greater than external pressure all the time, inside in order to reach the unable terminal box that gets into of combustible gas, be in the safety ring all the time, compare with increase an ampere type terminal box, safer.
