Abstract
For a circuit breaker for medium voltage switchgear equipment, comprising: a switch shaft, for an actuation movement being delivered to the moving contact of the switch pole of described circuit breaker; One auxiliary switch (1), can be controlled by described switch shaft and comprise an auxiliary switch shaft (3), for handle the control element of described circuit breaker; And a position indication (6) of described circuit breaker, can be controlled by described switch shaft, in order to improve this circuit breaker, make its structure simple, with low cost, the utility model proposes following solution: described position indication (6) is arranged on described auxiliary switch shaft (3).
Description
Technical field
The utility model relates to a kind of circuit breaker for medium voltage switchgear equipment, comprising:
-one switch shaft, for an actuation movement being delivered to the moving contact of the switch pole of described circuit breaker,
-one auxiliary switch, can be controlled by described switch shaft and comprise an auxiliary switch shaft, 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.The actuation movement of drive unit is delivered to by switch shaft on the moving contact of the switch pole of circuit breaker by this circuit breaker, switches on or off with this electric current 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, for handling the control element of circuit breaker, such as solenoid, release, for implementing switch etc. of switching manipulation to motor driver.Known circuit breaker also comprises and connecting and the position indication that can be controlled by this switch shaft with switch shaft through leverage, and it is for indicating the on off state of circuit breaker for being in outside user, namely circuit breaker is in on-state or off-state.
Utility model content
The purpose of this utility model improves the circuit breaker of aforementioned type, makes its structure simple, with low cost.
For the circuit breaker of aforementioned type, the utility model in order to reach the solution of this object is: described position indication is arranged on described auxiliary switch shaft.
To achieve these goals, the circuit breaker for medium voltage switchgear equipment of the present utility model comprises: a switch shaft, for an actuation movement being delivered to the moving contact of the switch pole of described circuit breaker; One auxiliary switch, can be controlled by described switch shaft and comprise an auxiliary switch shaft, for handle the control element of described circuit breaker; And a position indication of described circuit breaker, can be controlled by described switch shaft; Described position indication is arranged on described auxiliary switch shaft.
By position indication is arranged on auxiliary switch shaft, breaker structure can be made simple, with low cost, because so just do not need to use independent leverage to carry out control switch position indicating device, because the auxiliary switch shaft controlled by switch shaft makes position indication can change between its instruction on-state and the function of instruction off-state in the mode of motion, this can reduce required mechanical part quantity.
Accompanying drawing explanation
Accompanying drawing 1 is the auxiliary switch of the utility model circuit breaker.
Embodiment
Hereafter with embodiment form, the utility model is described in further detail with reference to the accompanying drawings.
Accompanying drawing is the auxiliary switch 1 for the circuit breaker of medium voltage switchgear equipment, further diagram is not done for this circuit breaker accompanying drawing, auxiliary switch 1 has a row switch sheet 2, these switch plates can be changed between a first state and a second state under auxiliary switch shaft 3 acts on, can to such as solenoid, trigger switch, carry out switching manipulation or manipulation for implementing the elements such as the switch of switching manipulation to the motor driver of circuit breaker by these switch plates.For this reason, auxiliary switch shaft 3 is through switch shaft (not shown) mechanical attachment of leverage 4 with described circuit breaker, and thus when the switch shaft of circuit breaker rotates 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-torsion, and its surface is provided with the symbol 7 representing circuit breaker off-state and the symbol 8 representing closing of power circuit breaker state, auxiliary switch 1 is installed to after below control panel that circuit breaker is provided with corresponding form, user just can one of them symbol 7 or 8 of externally visibly position indication 6, so just can according to the position of killer switch axle and the position according to the auxiliary switch shaft 3 connected with killer switch axle through leverage, indicate the corresponding state of circuit breaker, namely, circuit breaker is in the on-state that contact system closes or the off-state being in contact system disconnection.
