Abstract
The utility model discloses a 10kV line vacuum switch, comprising a multi-contact rotating switch. The multi-contact rotating switch is arranged outside an equipment box and comprises a plurality of wiring contacts which are connected with secondary coil tap lines of a current transformer in the equipment box; the multi-contact rotating switch is provided with gear identification. In the 10kV line vacuum switch, the secondary coil tap lines of the current transformer in the original equipment box are connected with the multi-contact rotating switch which is arranged outside the equipment box, if parameters of the protected line change, and when the protecting range needs to be readjusted, the multi-contact rotating switch rotates to a needed specific position after a lamp rod is disconnected with the switch, then the switch is switched on to supply power, and the whole process can be finished in a plurality of minutes, so that the 10kV line vacuum switch is convenient and practical, realizes convenient adjustment, and achieves the purposes that the line is effectively protected, the equipment is safe and the tripping of a super substation is not achieved.
Description
Technical field
The utility model belongs to power circuit controller switching equipment technical field, is specifically related to a kind of 10kv circuit vacuum switch.
Background technology
On the 10kv power circuit, all on the line pole in different locations, vacuum switch is installed, its objective is: on-load drawing, convenient maintenance; Provide short-circuit protection to a certain section circuit; Improve line walking efficient, reduce labour intensity.At present, 10kv circuit vacuum switch actual motion effect is very undesirable, and main cause is that vacuum switch protection definite value is selected inconvenience, causes vacuum switch protection range and circuit actual conditions not to be inconsistent.Because vacuum switch definite value protection is at present adjusted; be to make up mutually by the wiring on the Current Transformer Secondary coil tap terminal board in the equipment box to realize; bother very much; vacuum switch on the electric pole is because relatively side installation of support; make equipment unsettled,, at first need to have a power failure as need adjustment protection definite value; then vacuum switch is hung down, adjust.In order to make circuit normal duty when operation, the mistrip phenomenon does not appear in vacuum switch, often initial protection definite value is put in maximum; such result is once circuit has short trouble; vacuum switch is refused tripping operation, and accident is bypassed the immediate leadership to transformer station, will cause wider power failure.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of safety and stability, vacuum switch protection definite value easy to adjust, be convenient to operate, the effective 10kv circuit vacuum switch of protection circuit.
Realize that the technical scheme that the purpose of this utility model adopted is: a kind of 10kv circuit vacuum switch, comprise the multiconductor rotary switch, described multiconductor rotary switch is arranged on outside the equipment box, described multiconductor rotary switch comprises a plurality of wiring contact, described wiring contact is connected with Current Transformer Secondary coil tap line in the equipment box, and the gear sign is set on the described multiconductor rotary switch.
Because the utility model is adjusted inconvenient at 10kv circuit vacuum switch protection definite value; be difficult to situation about matching with the power circuit actual needs; Current Transformer Secondary coil tap line in the original equipment casing is connected with the multiconductor rotary switch; and the multiconductor rotary switch is installed on the equipment box outside; if protected line parameter circuit value changes; in the time of need readjusting protection range; after stepping on the bar cut-off switch; the multiconductor rotary switch is rotated on the definite value position that needs; then switch closes a floodgate and send; can finish in a few minutes; convenient and practical; realize making things convenient for adjustment, reached effective protection circuit; device security, and the purpose of the transformer station's tripping operation of not bypassing the immediate leadership.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the structural representation of multiconductor rotary switch of the present utility model.
Embodiment
As Fig. 1, shown in Figure 2: a kind of 10kv circuit vacuum switch, comprise multiconductor rotary switch 1, described multiconductor rotary switch 1 is arranged on outside the equipment box 2, described multiconductor rotary switch 1 comprises a plurality of wiring contact 3, described wiring contact 3 is connected with Current Transformer Secondary coil tap line in the equipment box, and gear sign 4 is set on the described multiconductor rotary switch 1.
At first; the circuit actual load situation of vacuum switch is installed as required; circuit distance and wire type; calculate the maximum short circuit current of this circuit; and in conjunction with transformer station's ladder protection scheme and following load increase situation; make the protection range of vacuum switch; for example protect definite value for 100/5,50/5,3,0/5 three; minimum gear adapts to the maximum demand when preload and seasonal variety; the middle-grade adaptation double maximum demand of loading in the future, maximum gear adapts to the needs of line conductor full-load run.The multiconductor rotary switch 1 that will configure protection range then is by interior corresponding connection of Current Transformer Secondary coil tap line of its wiring contact and equipment box; and the multiconductor rotary switch is installed on equipment box 2 outsides; if protected line parameter circuit value changes; in the time of need readjusting protection range; after stepping on the bar cut-off switch; multiconductor rotary switch 1 is rotated to the gear sign 4 that needs; to arrive the protection definite value that needs; then switch closes a floodgate and send; can finish in a few minutes; like this; do not need to make up the adjustment that realizes vacuum switch protection definite value mutually by the wiring on the Current Transformer Secondary coil tap terminal board in the equipment box again; only need the multiconductor rotary switch of operating equipment case outside to get final product, convenient and practical.
