Electromagnetic inducers are respectively connected to the A-phase power transmission line, the B-phase power transmission line, and the C-phase power transmission line; a fixing plate arranged below the vacuum circuit breaker is arranged at the electric pole and three electromagnetic induction indication lamps are arranged at the fixing plate; and each of the electromagnetic inducers is connected with one electromagnetic induction indication lamp respectively by one lead. The provided apparatus based on the reasonable design has the simple structure. On the basis of the existing 10-kV power supply line, the three electromagnetic inducers and three electromagnetic induction indication lamps are added. Therefore, the worker can determine whether each phase line is disconnected visually, thereby fully improving security of the maintenance operation.
Description
Technical field
The utility model belongs to power industry supply line technical field, relates in particular to a kind of 10kV supply line break-make indicating device.
Background technology
At present, when Dui 10kV supply line keeps in repair, staff need to disconnect the vacuum circuit-breaker on electric pole just can carry out operation, the A of supply line, B, C three-phase do not have electromagnetic induction indicator light, when using insulating bar disconnecting switch operation, often occur the actual not disconnection of isolating switch of a certain phase on vacuum circuit-breaker, staff keeps in repair will be dangerous, also occurred this serious accident several times.Therefore, this problem of not indicating vacuum switch whether to disconnect is needed badly and is resolved.
Utility model content
The utility model, in order to solve weak point of the prior art, provides a kind of reasonable in design, simple in structure, safe and reliable 10kV supply line break-make indicating device.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: 10kV supply line break-make indicating device, comprise the vacuum circuit-breaker being located on electric pole, three isolating switches on vacuum circuit-breaker are connected with respectively A phase power transmission line, B phase power transmission line and C phase power transmission line, described A phase power transmission line, on B phase power transmission line and C phase power transmission line, be connected with respectively an electromagnetic inductor, electric pole is provided with the fixed head that is positioned at vacuum circuit-breaker below, fixed head is provided with three electromagnetic induction indicator lights, each electromagnetic inductor is connected with an electromagnetic induction indicator light by a wire respectively.
Described fixed head is provided with installing hole, in installing hole, be equipped with the fastening ring flat-plate being centered around on electric pole, the openend of fastening ring flat-plate is fixed on fixed head on electric pole by trip bolt, described three electromagnetic induction indicator lights from top to bottom arrange successively, and fixed head top is provided with the rain cover being positioned at directly over electromagnetic induction indicator light.
Adopt technique scheme, 10kV supply line is when normal operation, and isolating switch is closed, three equal light yellows of electromagnetic induction indicator light; When overhauling, use insulating bar that three isolating switches are disconnected, when three electromagnetic induction indicator lights all extinguish, can determine that whole transmission line disconnects, staff can carry out line maintenance operation like this.Fixed head is fixed on electric pole by fastening ring flat-plate and trip bolt, is convenient to like this dismounting, and electromagnetic induction indicator light is vertically arranged, can reduce like this area of rain cover.Rain cover plays the effect that effective protection electromagnetic induction indicator light is not exposed to the sun and rain.
The utility model is simple in structure, reasonable in design, in existing 10kV supply line, adds three electromagnetic inductors and three electromagnetic induction indicator lights, makes staff judge that more intuitively whether every phase line disconnects, and has fully improved the fail safe of upkeep operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1,10kV of the present utility model supply line break-make indicating device, comprise the vacuum circuit-breaker 2 being located on electric pole 1, three isolating switches 3 on vacuum circuit-breaker 2 are connected with respectively A phase power transmission line 4, B phase power transmission line 5 and C phase power transmission line 6, on A phase power transmission line 4, B phase power transmission line 5 and C phase power transmission line 6, be connected with respectively an electromagnetic inductor 7, electric pole 1 is provided with the fixed head 8 that is positioned at vacuum circuit-breaker 2 belows, fixed head 8 is provided with three electromagnetic induction indicator lights 9, and each electromagnetic inductor 7 is connected with an electromagnetic induction indicator light 9 by a wire respectively.
