Abstract
A live testing rod of a high voltage switch contact resistor comprises an insulating rod, an insulating plate, probes and a number-off device wherein the insulating plate is fixedly arranged at the top end of the insulating rod, two ends of the insulating plate are provided with the probes, the number-off device is arranged at the upper part of the insulating rod, and the number-off device is electrically connected with the probes. Compared with the prior art, the live testing rod has the advantages that the structure is simple, the use is convenient, the cost is low, and the high voltage switch contact resistor can be tested without power failure.
Description
Technical field
The utility model relates to high-voltage switch gear contact resistance technical field of measurement and test, is specifically related to a kind of high-voltage switch gear contact resistance live testing bar.
Background technology
Army uses high-voltage switch gear in the high voltage substation, as isolating switch, disconnector etc., all will carry out the contact resistance test to these high-voltage switch gears every year, and the connection terminal of this need of work in the high-voltage switch gear both sides respectively connects two balanced bridge p-wires, measures contact resistance.Because porcelain equipment No climbing, therefore present maintainer is when measuring the contact resistance of high-voltage switch gear, two six meters fork ladders are set up in employing in the isolating switch both sides, two maintainers are being with p-wire binding clip climbing ladder to carry out wiring, need for a long time, not only influence work efficiency and work quality, and can have certain danger.The patent No. is that 201020151728.1 utility model patent discloses a kind of high-voltage switch gear contact resistance reference test bar, and it is simple in structure, easy to use, need not to set up, climb the contact resistance that the fork ladder just can be measured high-voltage switch gear, high efficiency, and security performance is good.But this patent is being carried out the contact resistance test to high-voltage switch gear, the operation that must have a power failure, and need two people and two such reference test bar co-ordinations, and just can finish test, not only waste time and energy, and the influence power supply.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of simple in structure, with low cost, high-voltage switch gear contact resistance live testing bar that can hot line job is provided.
Its technical scheme is: comprise insulating bar, insulcrete, probe and figures-giving calculator, described insulating bar top is fixed with insulcrete, and the insulcrete two ends are equipped with probe, and described figures-giving calculator is installed in insulating bar top; Figures-giving calculator is electrically connected with probe.
Wherein, described figures-giving calculator comprises tension measuring circuit, speech processing circuit, amplifying circuit, power circuit and loudspeaker, described tension measuring circuit, speech processing circuit, amplifying circuit and loudspeaker are in sequential series the connection, and described power circuit is connected with tension measuring circuit, speech processing circuit and amplifying circuit respectively; The input end of tension measuring circuit is electrically connected probe.Described power circuit is an accumulator.
The utility model has simple in structure, easy to use, with low cost and can be in the advantage that does not have a power failure the high-voltage switch gear contact resistance is tested compared with prior art.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the figures-giving calculator circuit block diagram of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1-Fig. 2, a kind of high-voltage switch gear contact resistance live testing bar comprises insulating bar 1, insulcrete 2, probe 3 and figures-giving calculator 4, and described insulating bar 1 top is fixed with insulcrete 2, insulcrete 2 two ends are equipped with probe 3, and described figures-giving calculator 4 is installed in insulating bar 1 top; Figures-giving calculator 4 is electrically connected with probe 3.Wherein, described figures-giving calculator 4 comprises tension measuring circuit 41, speech processing circuit 42, amplifying circuit 43, power circuit 45 and loudspeaker 44, described tension measuring circuit 41, speech processing circuit 42, amplifying circuit 43 and loudspeaker 44 are in sequential series the connection, and described power circuit 45 is connected with tension measuring circuit 41, speech processing circuit 42 and amplifying circuit 43 respectively; The input end of tension measuring circuit 41 is electrically connected probe 3.Described power circuit 45 is an accumulator.
During use, one people holds insulating bar 1 bottom, two probes 3 are touched the high-voltage switch gear two ends, at this moment, tension measuring circuit 41 promptly can read the magnitude of voltage at high-voltage switch gear two ends, and this numerical value sends amplifying circuit 43 to and amplifies after handling by speech processing circuit 42, by loudspeaker 44 count offs, the staff can calculate the contact resistance of high-voltage switch gear by the voltage value of quoting at last.Thereby reached the purpose that does not have a power failure the high-voltage switch gear contact resistance is tested.
