Abstract
The utility model belongs to a production facility of an electric power system, in particular to an on-off state display of a sealed type isolation switch, which is characterized in that three stroke switches are respectively arranged at a crank arm part of a three-phase connecting rod of an isolation switch operation mechanism, i.e. one stroke switch is arranged on each phase in a way of serial connection, a red lamp is connected in series on a pair of normally-open auxiliary joints of the stroke switch, a green lamp is connected in series on a pair of normally-closed auxiliary joints of the stroke switch, and both the red lamp and the green lamp are arranged in an obvious position capable of being seen by people. The utility model realizes the capability of prompting the on-off position of the isolation switch in any state, avoids the artificial misoperation, eliminates the accident potential, and ensures the stability and the reliability of the electric power system.
Description
Technical field:
The utility model belongs to the electric power system production facility, is specifically related to a kind of closed isolating switch deciliter.
Background technology:
At present, what integrated automation converting station (institute) was installed usually is gas insulated metal enclosed swit chgear, and the 220kV combined electrical apparatus is the phase-splitting operating mechanism, has " five is anti-" operating function.After operation a period of time, its " five anti-" operating function lost efficacy, when being embodied in normal operation, can not show its electrical equipment interlock normally whether.The circuit breaker of gas insulated metal enclosed swit chgear, isolating switch and earthing isolator all seal, its dynamic and static contact can not be significantly in sight, when normal running, if the operating mechanism link pin takes place to come off, the branch of dynamic and static contact, close variation and can not obviously reflect, operating personnel's false judgment phenomenon can take place.
If whether will detect " five is anti-" operating function effective, after needing to have a power failure,, confirm whether the electrical equipment interlocking plays a role by the electric operating disconnecting link.If during maintenance, because maintainer's careless omission does not expose isolating switch the operating mechanism link three-phase and all connects, and can not point out threephase switch whole opening and closing in place, cause the misoperation and the erroneous judgement of band ground disconnecting link and combined floodgate or charged and ground connection disconnecting link disconnected easily, thereby cause the electric short circuit accident.
Summary of the invention:
The utility model aims to provide and can obviously show whether effective closure formula isolating switch deciliter of " five is anti-" operating function.
The technical solution of the utility model is: it is characterized in that at isolator operating mechanism three-phase connecting rod connecting lever place three travel switches being installed respectively, be that each goes up the travel switch that all is installed in series mutually, a pair of red colored lamp of connecting on the auxiliary contact of often opening of travel switch, green light of series connection on a pair of normally closed auxiliary contact of travel switch, red colored lamp, green light are installed in the visibility point that people can see.
The utility model can intuitively be pointed out the operations staff, and isolating switch is in "on" position.Can show the isolating switch three-phase separating brake normally closed auxiliary contact closure state of travel switch that puts in place equally.If operating mechanism for some reason can not electric operating, also can effectively show deciliter state of isolating switch.
The utility model has realized can both pointing out deciliter position of isolating switch under any state, avoided artificial misoperation, has eliminated accident potential, has guaranteed the reliable and stable of electric power system.
Description of drawings:
Fig. 1 is the circuit diagram of the utility model embodiment.
Among the figure: the k-air switch, a, b, c-often open auxiliary contact, a1, b1, the normally closed auxiliary contact of c1-, HD-red colored lamp, LD-green light, R1, R2-resistance.
Embodiment:
Embodiment: shown in Figure 1, present embodiment carries out improved in existing 220kV combined electrical apparatus, promptly three travel switches are installed respectively at isolator operating mechanism three-phase connecting rod connecting lever place, be that each goes up the travel switch that all is installed in series mutually, a pair of red colored lamp of connecting on the auxiliary contact of often opening of travel switch, green light of series connection on a pair of normally closed auxiliary contact of travel switch, red colored lamp, green light are installed in the visibility point that people can see.The model of isolating switch is (ZF6-252-FDS) fast; The model of isolating switch is
(ZF6-252-DS); The model of earthing isolator is (ZF6-252-ES); The model of travel switch is (JLXK
1-111).
