Abstract
A sulfur hexafluoride ultra-high voltage resistive small-current on-off switch comprises the following components: a housing, a static contact, a moving contact, an insulation pull rod, a conductor shielding cover, a shielding cover, a guiding rod, a return spring, a baffle and a conductor. The utility model is characterized in that: the insulation pull rod is connected with the moving contact in the conductor shielding cover; the static contact provided in the shielding cover is connected with the guiding rod; the return spring is provided on the guiding rod; and the baffle is provided with the conductor which realizes the introducing in and out of the current. According to the utility model, the high-voltage resistor device is automatically withdrawn after putting in a certain time period through onetime continuous on-off operation, thereby ensuring that the resistor device is still in an uncharged state after the switching-off operation of the circuit breaker. Furthermore bearing a recovery voltage by the circuit breaker with a larger operating range in the on-off operation process can be ensured. Furthermore the sulfur hexafluoride ultra-high voltage resistive small-current on-off switch has the following advantages: simple structure, high insulation level and excellent performance.
Description
Technical field
The utility model relates to the high-voltage switch gear technical field, particularly a kind ofly closes switch-dividing for the input of elements such as switching-on resistance in superhigh pressure or the extra-high voltage electric power system or the resistive little electric current of sulphur hexafluoride ultra high voltage that withdraws from.
Background technology
Close closing overvoltage, the common configuration switching-on resistance that needs that the process of closing produces in order to reduce superhigh pressure or extra-high voltage electric power system break road device, thereby need corresponding resistance feeding device, present switching-on resistance feeding device and contact of breaker are synchronized with the movement, the resistance feeding device of this structure makes resistance device still be in electriferous state after breaker switching-on operation is finished, and cut-off in the operating process with less opening apart from bearing recovery voltage at circuit breaker, its fail safe is poor.
Summary of the invention
The purpose of this utility model provides and a kind ofly withdraws from automatically after can dividing closing operation that the high-tension resistive device is dropped into a period of time by one-time continuous, guarantee that resistance device is in not electriferous state after breaker switching-on operation is finished, and can guarantee that circuit breaker cut-offs and make it close switch-dividing in the operating process with bigger opening apart from the resistive little electric current of sulphur hexafluoride ultra high voltage that bears recovery voltage.
The utility model is to realize like this, it comprises housing, fixed contact, moving contact, insulated tension pole, conductor screen cover, radome, guide post, back-moving spring, dividing plate and conductor, moving contact in it is characterized in that insulated tension pole and being arranged on the conductor screen cover is connected, the fixed contact that is arranged in the radome is connected with guide post, guide post is provided with back-moving spring, and dividing plate is provided with the conductor of realizing that electric current is introduced and drawn.
The utility model withdraws from after can the high-tension resistive device being dropped into a period of time by disposable continuous minute closing operation automatically, thereby guarantee that resistance device still is in not electriferous state after breaker switching-on operation is finished, and can guarantee that circuit breaker cut-offs it is opened apart from bearing recovery voltage with bigger, have simple in structure, the advantage of insulation level height, function admirable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described;
Fig. 1 is the structural representation that the resistive little electric current of sulphur hexafluoride ultra high voltage closes switch-dividing.
Embodiment
As shown in Figure 1, the resistive little electric current of sulphur hexafluoride ultra high voltage closes switch-dividing and comprises housing 1, fixed contact 2, moving contact 3, insulated tension pole 4, conductor screen cover 5, radome 6, guide post 7, back-moving spring 8, dividing plate 9 and conductor 10, insulated tension pole 4 is connected with moving contact 3 in being arranged on conductor screen cover 5, the fixed contact 2 that is arranged in the radome 6 is connected with guide post 7, guide post 7 is provided with back-moving spring 8, dividing plate 9 is provided with the conductor 10 of realizing that electric current is introduced and drawn, its operation principle is that fixed contact 2 drives motion by insulated tension pole 4 by operating mechanism in making process, finish closing operation, give back-moving spring 8 energy storage of fixed contact 2 sides simultaneously, break away from contact between insulated tension pole 4 and operating mechanism after closing a floodgate on earth, back-moving spring 8 rebounds moving contact 3, realize sub-switching operation, thereby realize closing the branch operation continuously, close insulation one performance of switch-dividing in order to improve this little electric current in final separating brake position, be provided with suitable radome 6, introduce and draw by the 10 realization electric currents of the conductor on the dividing plate 9.
