Circuit breaker device and switching-on and switching-off detection device and method

Abstract

The invention is suitable for the technical field of circuit breakers, and provides a circuit breaker device and a switching-on and switching-off detection device and method. The device comprises a housing, a telescoping rod, wires, a connector, a slide rheostat, an indicating lamp, a junction box, a metal ring, and a connecting nut; one end of each of the two wires is electrically connected withthe connector while the other end is electrically connected with an indicating lamp after being connected with a slide rheostat in series; the junction box is opened, a notch is formed in the connecting wire on one side of the circuit breaker, the metal ring is connected with the connecting wire, the sliding rheostat is adjusted, the connector is connected with the connecting nut after the resistance value of the sliding rheostat is adjusted to be maximum, and whether the indicator lamp is lighted or not is observed; if not, the resistance value of the slide rheostat is adjusted, the indicatorlight is observed; if the indicator light does not react all the time, the circuit breaker is in a disconnected state; if the indicator light reacts, the circuit breaker is in a connected state, andthe junction box is fixed to the circuit breaker connecting line; so that the problems that the circuit breaker needs to be disassembled and use is inconvenient in a traditional detection mode are solved.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker detection, and in particular relates to a circuit breaker device, an opening and closing detection device and a method. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. [0003] In order to avoid circuit damage, the current circuit breaker detection device generally needs to disassemble the circuit breaker when detecting the opening and closing status of the circuit breaker, and connect the detection device to the connection terminals...
