Description
Technical field
The utility model relates to insulation and covers safety appliance, specifically transformer neutral point test of lightning arrester insulating shielding device.
Background technology
When main transformer neutral point test of lightning arrester is carried out at scene, because trial voltage is higher, neutral point discharge gap, apart from closer, is just discharged by discharging gap when causing magnitude of voltage not reach requirement trial voltage over the ground, and test cannot normally be carried out.Prior art is that before test, discharging gap is removed by staff, eliminates the impact of discharging gap on test, is recovered by discharging gap again, thus reach the object of test after off-test.
Because main transformer neutral point lightning arrester distance ground is higher, staff needs to ascend a height by discharging gap dismounting and disconnects test pressurized line, add the risk of high-rise working and high falling, and in process of the test, likely cause test pressurized line to come off, causing repeats to ascend a height carries out wiring, cause the time of whole process long, the waste working time, reduce work efficiency.
Utility model content
The purpose of this utility model provides the transformer neutral point test of lightning arrester insulating shielding device that a kind of structure is simple, easy to operate, screening effect is good.
The technical scheme realizing the utility model object is:
Transformer neutral point test of lightning arrester insulating shielding device, comprises overhead jointing clamp and insulating bar, also comprises connection fastener, epoxy resin rod and insulated shielding cover; Connection fastener is provided with two can the bayonet socket of folding, and the first bayonet socket mates equipped with overhead jointing clamp, and the second bayonet socket mates with epoxy resin rod and is equipped with; Insulated shielding cover is provided with and mates equipped through hole with epoxy resin rod, and one end of epoxy resin rod and the second bayonet socket are equipped with fixing, and the other end is fixedly connected with insulated shielding cover through the through hole on insulated shielding cover, plays the effect of fixed support insulated shielding cover.
Described insulated shielding cover is groove type, and itself and epoxy resin rod Relative vertical are arranged, and adopt rubber insulation material to make.
Described connection fastener is made up of metal material, is provided with two bayonet sockets, plays the effect fixing overhead jointing clamp and epoxy resin rod respectively.
Described overhead jointing clamp is prior art, and it is connected with one end of insulating bar, and the other end of insulating bar is provided with screw thread, can connect other insulating bar, can meet the requirement for height of overhead jointing clamp work.
The utility model transformer neutral point test of lightning arrester insulating shielding device, can according to the length of neutral point discharge gap, and the length of adjustment ring epoxy resins rod reaches test objective; According to the height of transformer neutral point lightning arrester, more piece insulating bar can also be connected and reaches use height.Realize mounting test wire simultaneously and install insulating boot two functions additional, whole process and test period foreshortened to about 2 minutes by original more than 10 minute, substantially reduced the activity duration, increased work efficiency, avoid work high above the ground risk simultaneously.
Use insulating shielding device of the present utility model at transformer neutral point test of lightning arrester, do not need repeatedly ascend a height wiring operation and remove discharging gap, avoid the risk of high-rise working and high falling.This device insulating property are good, safe and reliable, it is simple to operate to have, and can meet the requirement of high-potting.
