The utility model relates to power and distribution supply cable and power trans-former protection equipment in a kind of electric power system, and especially a kind of fuse switch electricity-detection grounding device, comprises electricity testing grounding ring body, ground loop fixture and insulating coating; Electricity testing grounding ring fixture is for being fixed on fuse switch main body lower end fusion tube mounting seat by electricity testing grounding ring body; Some is not insulated overcoat parcel electricity testing grounding ring body.The beneficial effects of the utility model are to provide a kind of fuse switch electricity-detection grounding device, this electricity-detection grounding device can adapt to varying environment, make maintenance personal can directly carry out maintenance or the replacing of fuse switch, greatly save manpower and material loss, no longer needed to make the destructive exposure of wire rod.
Description
Technical field
The utility model relates to power and distribution supply cable and power trans-former protection equipment in a kind of electric power system, especially a kind of fuse switch electricity-detection grounding device.
Background technology
Fuse switch is the most frequently used a kind of protective switch of the short circuit of 10kV distribution line branch line and distribution transformer; it have economy, easy to operate, adapt to the features such as outdoor environment is strong, be widely used in 10kV distribution line and distribution transformer primary side as protection and carry out equipment throwing, cut the use of operation.Fuse switch is arranged on 10kV distribution line branch line, can dwindle power failure range, because it has an obvious cut-off point, possess the function of isolating switch, create a safety work environment to maintenance section circuit and equipment, increased maintainer's safety; It is arranged on distribution transformer, can be used as the main protection of distribution transformer, so, in 10kV distribution line and distribution transformer, obtained universal.
Fuse switch on market does not have electricity-detection grounding device now, brings certain trouble to line maintenance and line upkeep; When overhauling at every turn or changing, the destructive exposure of wire rod be need to make, operation easier and the cost of overhaul increased.
Utility model content
The technical problems to be solved in the utility model is: a kind of fuse switch electricity-detection grounding device is provided.
For solving the problems of the technologies described above, the utility model provides following technical scheme: fuse switch electricity-detection grounding device, is characterized in that comprising electricity testing grounding ring body, ground loop fixture and insulating coating; Electricity testing grounding ring fixture is for being fixed on fuse switch main body lower end fusion tube mounting seat by electricity testing grounding ring body; Some is not insulated overcoat parcel electricity testing grounding ring body, during conducting transmission line maintenance, only need the exposed position that directly connects electricity testing grounding ring body can carry out electrical verification, adopt dedicated hook directly by fuse switch ground connection, no longer to need to make the destructive exposure of wire rod simultaneously.
Preferably, described electricity testing grounding ring fixture is bolt structure, for being connected to fix described electricity testing grounding ring body with the screw in the fusion tube mounting seat of fuse switch main body lower end.
Preferably, described electricity testing grounding ring body is that copper becomes, and electroplate, to strengthen conductivity and anticorrosive property.
Preferably, described insulating coating is silicon rubber.
Preferably, electricity testing grounding ring body can be various shape, as long as can form closed-loop path, from the convenience of manufacturing, considers, can be set to rectangle, square or circular.
The beneficial effects of the utility model are to provide a kind of fuse switch electricity-detection grounding device, this electricity-detection grounding device can adapt to varying environment, make maintenance personal can directly carry out maintenance or the replacing of fuse switch, greatly save manpower and material loss, no longer needed to make the destructive exposure of wire rod.
