Abstract

The invention discloses a circuit protecting device which aims to solve the problem of bad protection effect of a circuit protecting device in the prior art. The circuit protecting device includes a primary protection unit, a secondary protection unit, and an indicating unit, the primary protection unit is connected with an external mains supply, the external mains supply is connected with a load via the primary protection unit and the secondary protection unit, and the primary protection unit and the secondary protection unit are respectively connected with the indicating unit. The circuit protecting device solves the problem of bad protection effect of a circuit protecting device in the prior art by means of the arrangement of the primary protection unit and the secondary protection unit, and the fault of the circuit can be timely indicated by the indicating unit, the service life of the circuit protecting device is prolonged to a certain degree.

Description

technical field [0001] The invention relates to a protection device, in particular to a circuit protection device. Background technique [0002] Most of the existing overvoltage and overcurrent circuit protection devices use varistors with nonlinear characteristics. Therefore, damage or failure is easy to occur. If there is no restriction on the damaged varistor in the circuit, it will directly cause the main circuit to fail to supply power, and even cause electrical fires in severe cases. [0003] In order to reduce the possibility of varistor failure, part of the improvement is to increase the size and varistor voltage of the varistor, but this increases the cost of use and also increases the risk factor of the protected object to a certain extent. Contents of the invention [0004] In order to overcome the disadvantages of the poor protection effect of the circuit protection device in the prior art, the object of the present invention is to provide a circuit protection...
