Emergency latching device for low-voltage circuit breaker

Номер: CN103165353A
Принадлежит:

The invention relates to an emergency latching device for a low-voltage circuit breaker. The emergency latching device comprises a fourth connecting rod. One end of the fourth connecting rod is matched and connected with one end of a third connecting rod, and the other end of the fourth connecting rod abuts against a releasing half shaft of the low-voltage circuit breaker in a latching state. A second connecting rod is inserted into the other end of the third connecting rod, and is fixedly connected with one end of a first connecting rod. A fulcrum is arranged on the middle part of the third connecting rod. The other end of the first connecting rod penetrates through a support part, and is connected with a handle. The emergency latching device is characterized in that a normally-closed switch is connected with the first connecting rod, is connected in series with a circuit between a switching-off button and a shunt release, and is driven to be turned off by the first connecting rod in the ...

Circuit breaker auxiliary switch with shock-resistant structure

Номер: CN103367057A
Принадлежит:

The invention relates to a circuit breaker auxiliary switch with a shock-resistant structure. The circuit breaker auxiliary switch is characterized by comprising a cam with a section of equal curvature radius area and a microswitch, wherein the cam is arranged in a shell through a rotating shaft and can rotate around the rotating shaft; a roller of the microswitch is also arranged in the shell; a main shaft of an operating mechanism drives the cam to rotate through a connecting rod mechanism; when a circuit breaker is in a separating state, the roller is contacted with the equal curvature radius area of the cam; and when the circuit breaker is in a closing state, the roller is separated from the cam. According to the circuit breaker auxiliary switch, the roller stroke of the microswitch is kept in situ all the time due to the existence of the equal curvature radius area of the cam, so that the circuit breaker auxiliary switch has shock resistance.

Dual-position converting switch

Номер: CN102646524A
Принадлежит:

The invention provides a dual-position converting switch. The dual-position converting switch is characterized by comprising an operation mechanism, wherein the operation mechanism respectively controls two groups of symmetrical contact systems; each contact system comprises a connecting rod; one end of the connecting rod is connected with the operation mechanism, and the other end of the connecting rod is connected with a movable contact through a rotating shaft; and the movable contact rotates around the rotating shaft under the control of the operation mechanism. The dual-position converting switch provided by the invention utilizes a plastic-shell breaker design principle and a modularized design and thus has the advantages of simple and compact structure, small volume, reliable insulation, good arc extinguishing effect, high rated switching-on or switching-off capacity, and shock resistance and vibration resistance properties.
