Abstract
The utility model relates to a busbar bridge insulating isolation device which can effectively solve the problem of potential safety hazards caused by the reason that the existing busbar heating shrinkable tube is aged easily. According to a technical scheme, the busbar bridge insulating isolation device comprises an L-shaped box body, wherein the lower end of the box body is provided with a wire inlet; the left side of the box body is provided with a wire outlet; a port of the wire inlet is provided with insulating sleeves; and the box body is internally provided with multiple insulating clapboard groups corresponding to the insulating sleeves, as well as multiple groups of support column porcelain insulators. The busbar bridge insulating isolation device is novel and unique in structure, safe and convenient to use, excellent in insulation performance and long in service life.
Description
Technical field
The utility model relates to electrical installation, particularly a kind of bus bridge insulated isolated device.
Background technology
Bus bridge is connected with outdoor aerial circuit (or main transformer) for transformer station's indoor high-voltage cabinet uses product, mainly formed by shell body and bus, insulating part etc., wherein for guaranteeing between the interior bus of bus bridge and electrical distance relatively, now the general method that adds heat-shrink tube at bus skin that adopts guarantees, but because the bus skin adds the insulation effect of heat-shrink tube and the processing technology of manufacturer has close contacting, and the outer heat-shrink tube of the reason bus in elapsed time is easily aging, has great potential safety hazard.
Summary of the invention
For above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of bus bridge insulated isolated device, can effectively solve existing bus and add the easily aging problem that causes existing potential safety hazard of heat-shrink tube.
The technical scheme of its solution is, comprises casing, and casing is L shaped, and there is incoming line the casing lower end, and there is line outlet in the left side, and insulating sleeve is equipped with in the incoming line port, and many groups insulating barrier groups corresponding with insulating sleeve are housed in the casing, and many group support insulators are housed in the casing.
The utility model novel structure is unique, and is safe and convenient to use, good insulation preformance, long service life.
Description of drawings
Fig. 1 is main pseudosection of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Provided by Fig. 1, the utility model comprises casing, and casing 1 is L shaped, there is incoming line 2 casing 1 lower end, and there is line outlet 3 in the left side, and insulating sleeve 4 is equipped with in incoming line 2 ports, insulating barrier group 5 corresponding to many groups and insulating sleeve 4 is housed in the casing 1, many group support insulators 6 are housed in the casing.
In order to guarantee result of use, said insulating barrier group 5 has three groups, and incoming line 2 and line outlet 3 places respectively have one group, and the L shaped turning of casing 1 has one group, and every group of insulating barrier group consists of by three insulation boards uniformly at intervals.
Said support insulator 6 requires to be designed with two groups according to the national acceptance rules, places respectively two intervals of three insulating barrier groups, and support insulator is in angle steel 7 is weldingly fixed on casing 1.
The bus 8 that the utility model has been set with the isolating shrinkable sheath passes the insulating sleeve 4 at casing 1 incoming line 2 places, three insulation boards in a plurality of insulating barrier groups separate a bus, prevent between the bus because of the aging phenomenon that affects the integral insulation performance of outer layer insulation heat-shrink tube, guarantee between the interior bus of casing and electrical safety distance over the ground, many group support insulators are fixed on bus 8 in the casing 1, and the wall bushing 9 that bus 8 is installed on the indoor bridge opening of high voltage power distribution at line outlet 3 places links to each other.
The utility model is placed on the bus that skin installs sheath shrinkable sleeve additional in the bus bridge casing, and the many groups of warp insulating barriers separate a bus, can greatly prolong the useful life of bus, fail safe when guaranteeing to use, simple in structure, novel unique, be convenient to site operation and install, use safety, reliable, long service life.
