gis current transformer bird-proof junction box

Abstract

The invention discloses a bird preventing junction box of a GIS current transformer. The bird preventing junction box comprises a layer board. A plurality of threaded rods are fixedly installed on the layer board and provided with first nuts and second nuts in a matched mode, an upper box cover is arranged between the first nuts and the second nuts and makes contact with the first nuts and the second nuts, a lower box cover is arranged between the layer board and the upper box cover, the lower end of the lower box cover makes contact with the layer board, a first baffle is arranged on the circumferential ring of the inner wall of the upper end of the lower box cover, a second baffle is arranged on the circumferential ring of the outer wall of the lower end of the upper box cover, the first baffle is located above the second baffle, and the first baffle and the second baffle are located between the upper box cover and the lower box cover. The lower box cover is located on the layer board of the upper box cover all the time under the gravity effect, the height of the upper box cover is adjusted through the nuts, a wire outlet hole is formed in the lower box cover, a current transformer secondary line pipe is located in the box, corrosion caused by bird excrement is reduced, the defects of the short circuit and the open circuit of a secondary loop of the current transformer are overcome, and running hidden danger of electrical equipment is reduced.

Description

technical field [0001] The invention relates to a junction box, which is a bird-proof junction box for a GIS current transformer. Background technique [0002] GIS is the English abbreviation for Gas Insulated Totally Enclosed Combined Electrical Appliances, and GIS equipment is currently commonly used substation equipment in substations. The diameter of the box cover of the existing GIS current transformer junction box is too large, which easily causes birds to enter and build nests. Because birds nest in the secondary junction box of GIS current transformer, the harmful substances such as guano will corrode the secondary wiring. The secondary line pipe of the device passes directly under the upper box cover. Therefore, the secondary wire tube of the current transformer is easily corroded by bird droppings, resulting in short circuit and open circuit defects in the secondary circuit of the current transformer, which poses a great hidden danger to the safe operation of ele...
