Abstract
The utility model discloses a high-voltage isolating switch electric operating mechanism. The high-voltage isolating switch electric operating mechanism comprises a position splitting stroke switch and a position integrating stroke switch which are arranged on two sides of a pendulum shaft respectively. The pendulum shaft is provided with a bump whose outer end surface is an equal radius type arc surface, wherein the contact of the position splitting stroke switch or the position integrating stroke switch has a pushing and pressing type structure. According to the utility model, by replacing a pressing sheet on the pendulum shaft with the bump and replacing the position splitting stroke switch and the position integrating stroke switch with the pushing and pressing type structure, the equal radius type arc surface of the outer end surface of the bump is a control surface, and when an isolating switch is operated by the electric operating mechanism so as to be split or integrated in place, the bump is used to push and press the stroke switch contact and make the stroke switch contact disconnected so as to cut off the power circuit of a motor. At this time, the motor is rotated continuously under the effect of inertia, and the equal radius type arc surface has a sufficient length to always push and press the stroke switch contact and make the stroke switch contact maintained in the disconnected state until the rotation of the motor is stopped completely. The mechanism can be used to solve problems, such as motor overload burning, electric operating mechanism internal part damage, etc., due to the inertia of the motor well.
Description
[technical field]
The utility model relates to a kind of high-voltage electrical equipment, especially belongs to a kind of high voltage isolator motor-operating mechanism.
[background technology]
High voltage isolator is device for switching important in electrical system, and it and primary cut-out support the use, and guarantees High-Voltage Electrical Appliances and the safety of device when service work, plays the isolation voltage effect.Usually, high voltage isolator minute, feed motion controlled by motor-operating mechanism, as shown in Figure 1: when the balance staff a driven by motor d swings to the left or to the right, compressing tablet a1 can press down respectively minute position arm b1 or a co-bit arm c1, realizes the control to minute position and co-bit travel switch.But there are the following problems in actual applications for this motor-operating mechanism: minute, the co-bit travel switch is rocker style configuration, when compressing tablet is pushed down minute position arm b1 or co-bit arm c1, open and the electric power loop that cuts off motor d contact, but, existence due to motor inertia, the balance staff stall has a lag time, therefore, operating personnel usually will give one of balance staff and control lead in practice, if it is bad that lead is controlled, compressing tablet often there will be overshoot phenomenon and breaks minute position arm b1 or a co-bit arm c1, cause contact again closed motor obtain electric again the action, and cause motor overload, burn, damage the accidents such as motor-operating mechanism internal part.
[summary of the invention]
The problems referred to above that exist for solving prior art, the utility model aims to provide a kind of high voltage isolator motor-operating mechanism, this operating mechanism has very well been processed the motor inertia problem and has been controlled the contradiction between lead, thereby can effectively avoid causing motor overload, burns, damages the accidents such as motor-operating mechanism internal part.
For achieving the above object, the utility model has adopted following technical scheme: the structure of this high voltage isolator motor-operating mechanism, comprise minute position travel switch and the co-bit travel switch that are arranged on the balance staff both sides, it is characterized in that: the projection of radius arc faces such as thering is an outer face on described balance staff and be; The contact of described minute position travel switch or co-bit travel switch is the push-press type structure.
During concrete enforcement, described minute position travel switch or co-bit travel switch are the CSK-11 travel switch.
Beneficial effect: compared with prior art, the utility model changes the compressing tablet on balance staff into projection, after dividing a travel switch and co-bit travel switch to change the push-press type structure into, utilize the projection outer face etc. the radius arc face be chain of command, when the motor-operating mechanism disconnecting switch operation is closed or minute is put in place, projection pushing travel switch contact also makes its disconnection, and cuts off the motor power loop.Now, motor is rotated further under effect of inertia, still, due to etc. the radius arc mask enough length is arranged, pushing all the time the travel switch contact and making it remain on off-state, until the complete stall of motor.This mechanism has very well solved because of motor inertia, and the motor overload that may cause burns, damages the problems such as motor-operating mechanism internal part.
For deepening understanding of the present utility model, below in conjunction with accompanying drawing, by embodiment, be described in further detail.
[accompanying drawing explanation]
The perspective view that Fig. 1 is the prior art motor-operating mechanism.
The perspective view that Fig. 2 is an embodiment of the utility model.
In figure: balance staff 1, projection 2, co-bit travel switch 3, combined floodgate roller 31, minute position travel switch 4, motor 5.
[embodiment]
Referring to Fig. 2.This motor-operating mechanism comprises minute position travel switch 4 and the co-bit travel switch 3 that is arranged on balance staff 1 both sides.Balance staff 1 has the projection 2 that an outer face such as is at the radius arc face, and the contact of minute position travel switch 4 or co-bit travel switch 3 is the push-press type structure.During concrete enforcement, minute position travel switch 4 or co-bit travel switch 3 can adopt the CSK-11 travel switch.During work, take projection 2 etc. the radius arc face be the job control face, when the motor-operating mechanism disconnecting switch operation is closed or minute is put in place, the combined floodgate roller 31 of pushing CSK-11 travel switch, contact is disconnected and keep certain hour, thereby meet the needs of motor 5 inertia motions, thereby solve because of motor inertia, the motor overload that may cause burns, damages the problems such as motor-operating mechanism internal part.
Above-described embodiment is only for explaining the present utility model thinking, and should not be considered as the restriction to the utility model protection range, and any simple variant structure of having done according to embodiment all should be included the application's protection range in.
