Abstract
A circuit breaker for a medium voltage switchgear comprises a switch shaft used for transfering a driving motion to a movable contact of a switch of the circuit breaker, an auxiliary switch (1) which can be controlled by the switch shaft and includes an auxiliary switch shaft (3), a control element for controlling the circuit breaker and a switch position indicator (6) which can be controlled by the switch shaft. In order to improve the traditional circuit breaker, this circuit breaker is simple in structure and low in cost. The circuit breaker further provides the following arrangement: the switch position indicator (6) is disposed on the auxiliary switch shaft (3).
Description
Technical field
The present invention relates to a kind of circuit breaker for medium voltage switchgear equipment, comprising:
-one switch shaft is used for an actuation movement is delivered to the moving contact of the switch pole of described circuit breaker,
-one auxiliary switch can be controlled and be comprised an auxiliary switch shaft by described switch shaft, is used for handling the control element of described circuit breaker, and
One position indication of-described circuit breaker can be controlled by described switch shaft.
Background technology
A kind of like this circuit breaker for medium voltage switchgear equipment belongs to well-known prior art.This circuit breaker is delivered to the actuation movement of drive unit by switch shaft on the moving contact of switch pole of circuit breaker, switches on or off with this electric current that is transmitted through this circuit breaker and switchgear.This circuit breaker has auxiliary switch, and it comprises auxiliary switch shaft and can be controlled by the switch shaft of circuit breaker, is used for handling the control element of circuit breaker, for example solenoid, release, be used for switch of motor driver being implemented switching manipulation etc.Known circuit breaker also comprises the position indication that connects with switch shaft through leverage and can be controlled by this switch shaft, and it is used to and is in the on off state that outside user indicates circuit breaker, and namely circuit breaker is in on-state or off-state.
Summary of the invention
The objective of the invention is the circuit breaker of aforementioned type is improved, make it simple in structure, with low cost.
For the circuit breaker of aforementioned type, the present invention in order to the solution of reaching this purpose is: described position indication is arranged on described auxiliary switch shaft.
By position indication is arranged on auxiliary switch shaft, can make breaker structure simple, with low cost, because so just do not need to come the control switch position indicating device with independent leverage, because the auxiliary switch shaft that controlled by switch shaft makes position indication to change between the function of its indication on-state and indication off-state in the mode of motion, this can reduce needed mechanical part quantity.
Description of drawings
Accompanying drawing is the auxiliary switch of circuit breaker of the present invention.
Embodiment
Hereinafter the invention will be further described with the embodiment form with reference to the accompanying drawings.
Accompanying drawing is the auxiliary switch 1 that is used for the circuit breaker of medium voltage switchgear equipment, do not make further diagram for this circuit breaker accompanying drawing, auxiliary switch 1 has a row switch sheet 2, these switch plates can be changed between the first state and the second state under auxiliary switch shaft 3 effect, by these switch plates can to such as solenoid, trigger switch, the elements such as switch that are used for the motor driver of circuit breaker is implemented switching manipulation carry out switching manipulation or manipulation.For this reason, auxiliary switch shaft 3 is through switch shaft (not shown) mechanical attachment of leverage 4 with described circuit breaker, thereby when the switch shaft of circuit breaker rotated in switching process, the auxiliary switch shaft 3 of auxiliary switch 1 also can correspondingly rotate.auxiliary switch shaft 3 has position indication 6 at its end 5 away from switch plate 2, this position indication is connected with auxiliary switch shaft 3 anti-torsions, and its surface is provided with the symbol 7 of expression circuit breaker off-state and the symbol 8 of expression closing of power circuit breaker state, auxiliary switch 1 is installed to after circuit breaker is provided with below the control panel of corresponding form, the user just can see from the outside one of them symbol 7 or 8 of position indication 6, so just can be according to the position of killer switch axle and according to the position of the auxiliary switch shaft 3 that connects with the killer switch axle through leverage, indicate the corresponding state of circuit breaker, namely, circuit breaker is in the on-state of contact system closure or is in the off-state that contact system disconnects.
