Description
Technical field
The utility model relates to a kind of electric switch, particularly with the high-pressure vacuum breaker of arc-control device.
Background technology
The major loop of existing vacuum circuit-breaker and operating mechanism and controlling organization are independent setting, promptly are separately positioned on two independently in the casing.This setup exists and takes up space greatly, uses and installs conveniently inadequately, the complex structure of operating mechanism, action underaction, box sealing poor-performing, is subjected to external environment influence to produce problems such as condensation, influences its reliability and useful life.
In order to address the above problem, having at present all is integrated in operating mechanism, three-phase integrated insulation support seat, vacuum interrupter and control device in the seal case, operating mechanism and vacuum interrupter are connected as a single entity by main operation axle, insulated tension pole, have realized integrated configuration.But the defective that does not have auto-lock function between the electronic and manual closing mechanism that this circuit breaker also exists, meeting is disconnected because of misoperation causes circuit to dodge in short-term, can impact supply line.
Summary of the invention
The purpose of this utility model is to provide the outdoor high-voltage vacuum breaker of a kind of compact conformation, dependable performance.
The purpose of this utility model is achieved in that outdoor high-voltage vacuum breaker, comprise the three-phase integrated insulation support seat that is arranged in the seal case, be positioned at three-phase integrated insulation and support the vacuum interrupter of seat, operating mechanism, control device and major loop terminal, it is characterized in that also being provided with sky closes blocking mechanism, one end of the removable junction panel in this mechanism is connected with the operation panel of operating mechanism, the other end is connected with back-moving spring, on junction panel, be provided with movably block, block is provided with back-moving spring, block is oppositely arranged with the connecting lever that is installed on the on/off switch operating grip driving shaft, and is movable to the connecting lever below.Sky is set closes blocking mechanism, can effectively prevent misoperation, guarantee the reliability of vacuum circuit-breaker action.
The utility model has following characteristics compared with prior art: this circuit breaker have compact conformation, rationally, be active in one's movements reliable, operating mechanism, three-phase integrated insulation support seat, vacuum interrupter and control device all are integrated in the seal case, when effectively preventing condensation, can also prevent to improve the reliability of circuit breaker because of misoperation causes influence to supply line.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further auspicious stating:
As shown in Figure 1 and Figure 2, seal case 1 adopts the thick corrosion resistant plate of 2mm to make, be provided with 3 on two relative sidewall respectively into and out of line major loop terminal 2, the insulating sleeve 3 of major loop terminal outside adopts silastic material to make, and insulating sleeve becomes to be tightly connected with casing.Three channel insulation support seats that are fixed intervals mutually and are connected as a single entity 4 tilt 45 ° and are arranged in the casing, and three-phase vacuum interrupter 5 is separately positioned in the groove, its two ends by soft conductive strips 6 be connected into and out of the major loop terminal accordingly.Insulation is supported to be fixed with metallic support 7 on the outside groove bottom of seat, and the parts of control device and operating mechanism all are arranged on the support.Operation panel 9 in the operating mechanism on the main operation axle 8 directly is connected with the insulated tension pole 22 of vacuum interrupter, it is had be active in one's movements, and is simple in structure, the advantage that reliability is high.Operating mechanism mainly be by close, tripping spring 23,24, energy storage motor, closing coil, switching winding, formations such as transmission stop mechanism.The connect box that is used for uniform on the case lid periphery is connected with case lid with casing respectively by bolt 12 with the two ends of the curved pressure relief plate 11 of case lid 10.The benefit that case lid and casing is connected to one by pressure relief plate is when circuit breaker generation internal break fault, box house pressure sharply rises, can be with case lid jack-up and the pressure relief plate sweep is stretching, form the pressure release space between the case lid of jack-up and the casing, therefore case lid can not break away from casing, just can not cause potential safety hazard yet.
It is by junction panel 29 that the sky that is arranged on bottom half closes blocking mechanism, back-moving spring 25,26, block 27 constitutes, movably junction panel is provided with pilot hole 13, screw 14 passes this hole and is connected with box bottom, the end arm of junction panel one end is arranged on a side of the operation panel end axle 15 of operating mechanism, link with operation panel, the end arm of the other end is connected with back-moving spring 25, the other end of spring is connected on the projection 16 that is fixed in base plate, be arranged on the junction panel and can be with its block that moves 27, the bottom is provided with the projection that is inserted in the junction panel spacing hole, the connecting rod of one end is inserted in the hole of junction panel end arm, be with back-moving spring 26 on the connecting rod, both ends of the spring is against respectively between block and the junction panel end arm, block is oppositely arranged with the connecting lever 28 that is installed on the on/off switch operating grip driving shaft, can move to the connecting lever below with junction panel, also can move at the promotion lower edge of connecting lever 28 junction panel spacing hole 17.Sky is set to be closed blocking mechanism and can prevent the misoperation of closing a floodgate once more, operation principle is: behind the electronic combined floodgate of circuit breaker, the operation panel 9 of switching-on mechanism drives the empty junction panel that closes blocking mechanism and slides into dotted line position, the block that be installed on the junction panel this moment moves to the below that is installed on the connecting lever on the driving shaft with it, when at this moment operating the on/off switch operating grip that is connected as a single entity with driving shaft again, because connecting lever can not be rotated by stop limits, the operation of on/off switch operating grip is under an embargo, and has prevented empty feed motion.When circuit breaker is used on/off switch operating grip 30 closing by hands, the operation panel of switching-on mechanism drives the empty junction panel that closes blocking mechanism and slides into dotted line position, this moment, block was withstood by the connecting lever with on/off switch operating grip drive shaft turns, block moves to junction panel end arm direction at the promotion lower edge of connecting lever spacing hole, at this moment back-moving spring 26 is compressed, after closing by hand finishes, unclamp the on/off switch operating grip, connecting lever resets with driving shaft, block makes it closing operation again being inserted under the effect of back-moving spring bullet below the connecting lever.
The casing outside be provided be used to show the energy storage state and close, the pointer of gate-dividing state and energy storage handle, on/off switch operating grip etc., the control loop socket 18 that is arranged on the circuit breaker casing is the water proof type socket.All are arranged on to be between parts on the casing and the casing and are tightly connected.OCR coil 19 is adopted in the electric secondary of this circuit breaker protection loop, makes it have the syllogic defencive function, the safe operation of transmission line is provided more fully ensure.Also dispose parts such as lifting gold utensil 20, hygroscopic agent 21.
