Abstract
The utility model relates to a high-voltage indoor fuse dismounting device which comprises a hollow insulating rod (1). The device is characterized in that one side of the end part of the insulating rod (1) is provided with an arc-shaped fixed hoop (2); an arc-shaped movable hoop (3) is arranged in a way to be opposed to the arc-shaped fixed hoop (2); one end of the arc-shaped movable hoop (3) is connected with one end of a lever (4); the other end of the lever (4) is connected with one end of a stay cord (5); the other end of the stay cord (5) is provided with an operating handle (6); a pin axle (9) is arranged in a way to pass through a through hole (8) and an axle hole (7); the lever (4) is arranged inside the insulating rod (1) and can rotate around the pin axle (9); the operating handle (6) is arranged inside a slide chute (10) and can slide vertically; and the lever (4) can be driven to rotate around the pin axle (9) through the stay cord (5). The high-voltage indoor fuse dismounting device which is convenient to operate has great compatibility and is safe to use. Furthermore, the device enables a worker to be far away from a power source. The electric shock danger can be greatly reduced.
Description
Technical field
The utility model belongs to electric power tool class technical field, relates in particular to fuse replacer in a kind of transformer substation high voltage chamber.
Background technology
At present, in power domain, the interior 10kV of part Substation Station and 35kV high voltage potential transformer are connected with high voltage bus, adopt fuse apparatus, if break down, can cut off voltage in time to report to the police timely, and high-tension fuse is installed in high-tension switch cabinet, need people to enter switch cubicle or with hand dismounting fuse, have certain security risk.Some client's converting equipments have one group of high-tension fuse before access network system, and object is when customer equipment breaks down, can excise in time fault electrical network not to be impacted in order to avoid cause more large area blackout.This client's converting equipment is many is all the lower inlet wire mode of connection of taking, namely charged below converting equipment, and now if people enters hyperbaric chamber to change the words of fuse very dangerous, if but power failure replacing can cause other clients' power failure, and coverage is large.In existing instrument, only have a kind of similar scissor insulated clamp can carry out this work, but this instrument pliers is bimanualness, can not adjusting size, and can only operate the fuse of fixed voltage grade, therefore there is much inconvenience.As Fig. 1.If can invent a kind of instrument, can not enter and in high-tension switch cabinet or hyperbaric chamber, change fuse and can greatly reduce power failure range, therefore also can make operating personnel exempt from injury, invent a kind of instrument of can be simple and practical and can changing easily high-tension fuse and be necessary very much.
Summary of the invention
The utility model for overcome need in the past people directly change high-tension fuse dangerous drawback, fuse replacer in a kind of novel hyperbaric chamber is provided.Fuse replacer in a kind of hyperbaric chamber, include the insulating bar of a hollow, it is characterized in that: end one side of insulating bar arranges fixedly anchor ear of a circular arc, with the fixing relative circular arc activity anchor ear that is provided with of anchor ear of circular arc, circular arc fixedly anchor ear and circular arc activity anchor ear closure can form annulus, one end of circular arc activity anchor ear and one end of lever link together, the other end of lever is connected with one end of stay cord, the other end setting operation handle of stay cord, lever is provided with axis hole, on insulating bar, have through hole, by through hole and axis hole, install bearing pin, lever is arranged in insulating bar, and lever can rotate around bearing pin.The bottom of described insulating bar is provided with chute, and operating grip is located in chute and can slides up and down, and can around bearing pin, rotate by stay cord pull lever simultaneously.Under the effect of thick stick, circular arc activity anchor ear can around bearing pin rotation, fixedly anchor ear be closed with circular arc.The lever of described circular arc activity anchor ear one side is provided with spring, and the effect of spring is automatically circular arc activity anchor ear to be resetted.
Utility model is easy to operate, compatible strong, uses safety, and insulating bar and anchor ear all adopt insulating material, can stand 35kV high pressure, and backward compatible, and human body, away from power supply, greatly reduces the danger of electric shock.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is appearance structure schematic diagram of the present utility model.
embodiment:
With reference to accompanying drawing, fuse replacer in a kind of hyperbaric chamber, include the insulating bar 1 of a hollow, it is characterized in that: end one side of insulating bar 1 arranges fixedly anchor ear 2 of a circular arc, with the fixing relative circular arc activity anchor ear 3 that is provided with of anchor ear 2 of circular arc, circular arc fixedly anchor ear 2 can form annulus with circular arc activity anchor ear 3 closures, one end of circular arc activity anchor ear 3 and one end of lever 4 link together, the other end of lever 4 is connected with one end of stay cord 5, the other end setting operation handle 6 of stay cord 5, lever 4 is provided with axis hole 7, on insulating bar 1, have through hole 8, by through hole 6 and axis hole 7, install bearing pin 9, lever 4 is arranged in insulating bar 1, and lever 4 can rotate around bearing pin 9.The bottom of described insulating bar 1 is provided with chute 10, and operating grip 6 is located in chute 10 and can slides up and down, and can around bearing pin 9, rotate by stay cord 5 pull lever 4 simultaneously.Under the effect of lever 4, circular arc activity anchor ear 3 can rotate and fixing anchor ear 2 closures of circular arc around bearing pin 9.On the lever 4 of described circular arc activity anchor ear 3 one sides and be provided with spring 11 between insulating bar 1, the effect of spring 11 is automatically circular arc activity anchor ear 3 to be resetted.
During use, the circular arc that can utilize this replacer fixedly anchor ear 2 and circular arc activity anchor ear 3 embraces that fuse is pulled outwardly or move back inwards the effect that just can reach dismounting or fuse is installed.Not the used time under spring action for opening shape, stand-by.
This replacer carries out installation or removal process and convenient and strength-saving, compares only need one hand to operate with insulated clamp, has also guaranteed operating personnel's personal safety when greatly improving operating efficiency.
