Description

Technical Field

[0001] The present application relates to the technical field of releasers, and in particular to a releaser assembly. Background Art

[0002] Circuit breakers are commonly used components in the electrical field, used to connect and disconnect currents and provide protection for lines and equipment in the event of overcurrent or short circuits. Shunt releases are important internal accessories of circuit breakers;

[0003] When there is leakage in the line or a person is electrocuted, the vector sum of the current passing through the zero-sequence current transformer is not equal to zero. A voltage is generated on both sides of the secondary coil of the transformer and is amplified by the integrated circuit. When the set value is reached, the power supply is cut off within 0.1 second through the leakage release, thereby providing protection against electric shock and leakage.

[0004] For example, the patent with publication number CN207116350U specifically discloses a shunt release for a circuit breaker, including a base, a release, and a switch. When the circuit breaker trips, the tripping of the circuit breaker actuates the switch, causing the switch to disconnect the power supply circuit of the release, and the rapid disconnection of the electromagnetic mechanism circuit is achieved through the conversion of the rotating part of the circuit breaker.

[0005] Since the release is usually connected to the circuit breaker through multiple cables, including signal cables and electric wires, which are respectively used to control the release and energize the release, so as to facilitate the reception of power-off signals, and the wiring terminals of the existing release are usually exposed to the outside for convenient wiring, and the wiring terminals are easily sticky with a lot of dust when exposed to the outside for a long time, which is easy to cause poor contact. Therefore, it is necessary to design a release assembly to solve the above problem.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0008] The technical solution adopted by the present application to solve the technical problem is: a tripper assembly, belonging to the technical field of trippers. It mainly includes: a circuit breaker, the circuit breaker has an inclined surface; a tripper, the tripper is arranged on the circuit breaker; two sets of positioning members, the positioning members are installed on one side of the circuit breaker and one side of the tripper, and the positioning members have a buckle groove; a frame plate, the frame plate covers the circuit breaker; a transparent plate, the transparent plate is installed on the frame plate; two sets of sliding plug-ins, the two sets of sliding plug-ins are installed on the frame plate.

[0009] Furthermore, the frame plate has a protrusion.

[0010] Furthermore, a connection terminal is installed on the circuit breaker.

[0011] Furthermore, the transparent plate is provided with a through hole that matches the size of the cable connected to the wiring terminal, and a sealing ring is provided at the contact position between the through hole and the cable.

[0012] Furthermore, magnetic blocks are installed on both sides of the circuit breaker, and the contact position between the sliding plug-in and the magnetic blocks is set with magnetic material.

[0013] The beneficial effect of the present application is that the present application provides a release assembly, which, through the coordinated use of a sliding plug-in, a positioning piece, a magnetic block, a frame plate, a protrusion and a transparent plate, can better avoid excessive dust from sticking to the wiring terminals, thereby effectively ensuring the normal operation of the circuit breaker and the release.
