A kind of power box convenient for quick power off

Abstract

The invention discloses a power box easy to quickly power off, comprising a box body, an inner box, a box cover, a clamping strip, a lock block, a lock hole and an unlocking device. A trigger is disposed on the power box to solve a problem. In the case of a power box failure or a state in which the box cover cannot be opened smoothly such that a main switch cannot be turned off, the unlocking device disposed on the top of the power box can be inserted into the lock hole to start the trigger so as to achieve quick power off. The trigger firstly eliminates a transient overvoltage generated by apower failure by a power isolation device so as to prevent the transient overvoltage from causing serious damage to equipment and affecting household lines, and secondly drives the magnetic coil of alever power-off device by the power isolation device to generate a sufficient magnetic field to disconnect a circuit, so as to power off the power box quickly without turning on the power box.

Description

technical field [0001] The invention relates to the field of electric boxes, in particular to an electric box convenient for quick power off. Background technique [0002] The power box is installed at home for the management and control of household appliances and power lines. During normal operation, the circuit can be connected or disconnected by manual or automatic switch. It is convenient to manage the circuit by prompting or sending a signal when it deviates from the normal working state. When a circuit fault occurs, it is conducive to maintenance. The circuit breaker is the core component of the power box, which directly determines whether the entire power box can operate normally. The weakest link in the electrical system that is most likely to fail. When there is a problem with the circuit, it is often found that the circuit breaker cannot be normally opened and the power is cut off. In the field accident handling, the phenomenon of the circuit breaker refusal to tr...

[0002] The power box is installed at home for the management and control of household appliances and power lines. During normal operation, the circuit can be connected or disconnected by manual or automatic switch. It is convenient to manage the circuit by prompting or sending a signal when it deviates from the normal working state. When a circuit fault occurs, it is conducive to maintenance. The circuit breaker is the core component of the power box, which directly determines whether the entire power box can operate normally. The weakest link in the electrical system that is most likely to fail. When there is a problem with the circuit, it is often found that the circuit breaker cannot be normally opened and the power is cut off. In the field accident handling, the phenomenon of the circuit breaker refusal to trip is common, and because the power box is overloaded after operation It will cause the structure of the power box to be deformed by heat and cannot be opened smoothly. Once this problem occurs and the power cannot be cut off quickly, it will easily cause the overload operation of the power box and cause a secondary power accident. Based on the above premise, this case developed a fast power off. power box to solve this problem
