Problems solved by technology

[0004] This technical solution can ensure the safe disconnection of the circuit, and can detect the voltage and current values ​​in the circuit at the same time by controlling the disconnection of the circuit through a variety of power components, but the operation of the circuit breaker is too complicated through the control circuit of multiple components, and requires staff to operate, so it cannot be realized automatically. operation, the high cost of various original components is not conducive to mass production

Abstract

The invention belongs to the technical field of circuit protection, in particular to a high-voltage circuit breaker protector, comprising a frame body, a driving module and a driven module. The upperand lower surfaces of the frame body are respectively provided with two active modules; The frame is provided with a driven module; As the voltage increase, heat is generated to heat mercury, the T-shape insulating rod is moved upward to make the first contact disconnect from the second contact, the electromagnetic generator is stopped from supplying power, the brake rod is moved downward to drivethe upper bearing plate and the lower bearing plate to do opposite movement, and the two electric contact balls are separated under the action of the elastic rope, so that the main circuit is disconnected; When the temperature returns to normal, As mercury contract more slowly, the shrinkage of mercury is accelerated through the elastic force of the first spring and the gravity of the T-shaped insulating rod so that the first contact and the second contact are connected, the electromagnetic generator is normally powered, and the brake rod is moved upward to drive the upper bearing plate and the lower bearing plate to move in opposite directions, so that the two electric contact balls are contacted, thus realizing the automatic circuit opening and closing.

Description

technical field [0001] The invention belongs to the technical field of circuit protection, in particular to a high-voltage circuit breaker. Background technique [0002] Generally, a circuit breaker is an electrical protection device placed between a power source and a load device to protect the load device and circuit wires from fault currents that may be generated in the circuit. [0003] There are also some technical solutions for circuit breakers in the prior art. For example, a Chinese patent with application number 2017110070409 discloses a circuit breaker (TS), which is used to disconnect the circuit when an adjustable safety parameter is exceeded. Said circuit breaker comprises an electronic trigger unit (ETU) in which adjusted safety parameters are stored, comprising a movable sealing disc (3) covering at least part of the circuit breaker (TS), characterized in that said circuit breaker (TS) has sensors (5, 7), with which the first state of the sealing disc (3) can...
