An explosion-proof device for a circuit

Abstract

The invention discloses an explosion-proof device for a circuit, its structure includes explosion-proof junction box, junction box cover, wiring protection tube, At that front and rear end and the middle part of the right end of the explosion-proof terminal box, At that top end of the explosion-proof junction box, a junction box cover is locked. When the explosion-proof junction box is use, 1, thesealing property of the device can be realized through the junction sealing device and the assembled rub pad and the like, so that the device can better prevent external gas or debris from entering the inside of the device, influence the combustion and explosion triggering point of the device, ensure safety, and is convenient to use; 2, the device is provided with a pressure pumping device and ablocking ball, so that the device can realize unidirectional manual pressure pumping when in use, so that the device can conveniently make the inside of the junction box be in a vacuum state, and because of the vacuum negative pressure, the user can also access the flame retardant protective gas, so that the device can prevent the device from burning and exploding through the vacuum or the flame retardant protective gas.

Description

technical field [0001] The invention is an explosion-proof device for circuits, which belongs to the field of explosion-proof devices for circuits. Background technique [0002] When the circuit is in use, it is easy to cause the temperature of the circuit to rise sharply due to faults such as short circuit, which may easily lead to dangers such as combustion and explosion of the components around the circuit. In order to reduce and avoid these dangers, the circuit is often protected. , These devices for circuit protection are explosion-proof devices for circuits. [0003] When the traditional explosion-proof devices for circuits are used, 1. Electronic circuit board detection and control are often used for circuit explosion-proof, but because the circuit short-circuit trigger time is short, it is easy to cause sparks and other phenomena that the safety circuit board does not respond in time, and it is easy to cause the circuit board to appear. Danger and inconvenience of b...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an explosion-proof device for circuits to solve the problems of using traditional explosion-proof devices for circuits. The short trigger time may easily lead to sparks and other phenomena that the safety circuit board does not respond in time, which may easily lead to the danger and inconvenience of burning the circuit board; In explosive areas, it is easy to cause the device to be mixed with impurities or flammable and explosive gases, which will greatly reduce the trigger point of combustion and explosion when the circuit board is used, which will easily lead to danger.
