Abstract
The utility model discloses a load isolation switch operation mechanism device used for a high-voltage cabinet and capable of preventing error operation. The load isolation switch operation mechanism device includes a load isolation switch operation mechanism and an operation handle arranged on the load isolation switch operation mechanism. The load isolation switch operation mechanism device also includes an electromagnetic lock preventing the load isolation switch operation mechanism from on-load operation. The electromagnetic lock is arranged on a side of the load isolation switch operation mechanism and is provided with a pin roll used for limiting the operation handle. The load isolation switch operation mechanism is provided with a limiting hole corresponding to the pin roll. By adopting the electromagnetic lock, the high-voltage load isolation switch operation mechanism cannot be switched out in a condition with a load, so that error operation of on-load switching-out is avoided. The load isolation switch operation mechanism device used for the high-voltage cabinet and capable of preventing error operation is simple in operation and is safe and reliable, and can protect components in the high-voltage cabinet and operators effectively.
Description
Technical field
The utility model relates to high-voltage board technical field, especially relates to the fool proof load-break switch operating mechanism of a kind of high-voltage board device.
Background technology
At present increasing high-voltage capacitance cabinet by open become closed, when improving the protection of switch cubicle, also more and more safe problems have been brought, especially in the Problem process of high-pressure capacitance compensation cabinet, need to cut off capacitor box power supply, generally, the power supply of the direct cutoff high outgoing line cabinet of meeting, again operate high pressure capacitance compensation cashier's office in a shop load-break switch operating mechanism carry out disjunction, but often there is operating personnel's misoperation, when there is no separated high-voltage terminal cabinet power supply, directly pull off the load-break switch operating mechanism of compensating cabinet, the moment discharging and recharging at high-voltage capacitance cabinet operates a switch, not only can be larger to high-voltage capacitor and high voltage reactor damage, even there will be termination electric discharge, scaling loss components and parts, lead to larger electric accident, threaten operating personnel's life security.
As shown in Figure 4, for traditional high-voltage board load-break switch operating mechanism schematic diagram, during to high-voltage board Problem, by operating grip 5 operation, be arranged on the existing load-break switch operating mechanism 10 on door-plate 9, this kind of mode be without any protection, anyly can operate a switch per capita, be prone to misoperation, on-load is operated a switch and is happened occasionally, and security performance is low, easily causes security incident.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide the fool proof load-break switch operating mechanism of a kind of high-voltage board device, to reach, prevents misoperation, realizes the zero load object of operating a switch and controlling.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: the fool proof load-break switch operating mechanism of a kind of high-voltage board device, comprise load-break switch operating mechanism and be located at the operating grip on load-break switch operating mechanism, also comprise the electromagnetic lock that prevents the operation of load-break switch operating mechanism on-load, described electromagnetic lock is located at a side of load-break switch operating mechanism, electromagnetic lock is provided with for operating grip is carried out to spacing bearing pin, and on load-break switch operating mechanism, corresponding bearing pin is provided with spacing hole.
Described electromagnetic lock is fixed together by connector and load-break switch operating mechanism.
In described electromagnetic lock, be provided with control bearing pin and stretch out the control module operating with return.
The utility model compared with prior art; have the following advantages: by electromagnetic lock, high voltage load isolator operating mechanism cannot be operated a switch in the situation that having load; the misoperation of avoiding on-load to operate a switch; simple to operate; safe and reliable, effectively protect components and parts in high-voltage board and operating personnel's personal safety.

In figure: 1. load-break switch operating mechanism, 2. fastening bolt, 3. connector, 4. bearing pin, 5. operating grip, 6. switch rotating shaft, 7. electromagnetic lock, 8. set bolt, 9. door-plate, 10. existing load-break switch operating mechanism.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, the fool proof load-break switch operating mechanism of this high-voltage board device, comprises load-break switch operating mechanism 1 and prevents the electromagnetic lock 7 that load-break switch operating mechanism on-load operates; On load-break switch operating mechanism 1, by switch rotating shaft 6, be provided with operating grip 5, electromagnetic lock 7 is located at a side of load-break switch operating mechanism 1, electromagnetic lock 7 is fixed together with load-break switch operating mechanism 1 by fastening bolt 2 and connector 3, then by set bolt 8, load-break switch operating mechanism and electromagnetic lock integral body is fixed on the door-plate 9 of high-voltage board; Electromagnetic lock 7 is provided with for operating grip is carried out to spacing bearing pin 4, and on load-break switch operating mechanism 1, corresponding bearing pin 4 is provided with spacing hole.
Wherein, in electromagnetic lock 7, be provided with control bearing pin and stretch out the control module operating with return.
As shown in Figure 3, according to primary cut-out, in separating brake or closing position situation, control module is controlled electromagnetic lock coil and is obtained dead electricity; When primary cut-out is during in open position, electromagnetic lock coil obtains electric, and the bearing pin on electromagnetic lock is affected and got back to home position by magnetic force, and now load-break switch operating mechanism can operate by operating grip; On the contrary, when primary cut-out is during in closing position, electromagnetic lock coil losing electricity, bearing pin on electromagnetic lock rebounds and enters in load-break switch operating mechanism, stop the operating grip operation of load-break switch operating mechanism, load-break switch operating mechanism cannot be operated by on-load, prevent misoperation.
Can be according to different high-voltage boards, the auxiliary connection of electromagnetic lock secondary line is designed to different, realizes the different-effect of the electronic work of electromagnetic lock coil gain and loss when high-voltage circuit-breaker switching on-off position, reaches various fool proof orders, applied range.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
