Problems solved by technology

[0002] When the low-voltage pile head of the transformer is damaged and needs to be repaired or replaced, because the distance between the high-voltage and low-voltage pile heads is too small, the high-voltage pile head may be accidentally touched (the high-voltage pile head may be charged), which cannot meet the needs of safe operation. At the same time, some existing insulation baffles have a single size, occupy a lot of space during storage, and are inconvenient to carry and transport.

Abstract

The invention discloses an insulating isolation baffle plate, and the baffle plate comprises an outer baffle plate, wherein a containing cavity is formed in the outer baffle plate; an inner baffle plate which comprises a first telescopic baffle plate and a second telescopic baffle plate, wherein the first telescopic baffle plate and the second telescopic baffle plate are arranged in a staggered mode and connected through a rotating block, and the inner baffle plate is arranged in the containing cavity; a fixing part which comprises a connecting rod, a fixing pressing plate and a fixing box, wherein the connecting rod is rotationally arranged in the fixing box, the fixing pressing plate is hinged to one end of the connecting rod, the end, away from the connecting rod, of the fixing pressing plate is connected with a traction part, and the fixing part is arranged at the position of the fixing hole. Isolation of high-voltage and low-voltage pile heads of transformers of different sizes can be achieved through cooperation of the outer baffle plate and the inner baffle plate, the inner baffle plate is arranged in the containing cavity formed in the outer baffle plate, the size of the insulating isolation baffle plate can be effectively reduced, carrying is convenient, the fixing part is used for fixing the extending length of the inner baffle plate, so that the baffle plate is adapted to transformers of different sizes, and convenience and rapidness are achieved.

Description

technical field [0001] The invention relates to the technical field of insulating and isolating boards, in particular to an insulating and isolating baffle. Background technique [0002] When the low-voltage pile head of the transformer is damaged and needs to be repaired or replaced, because the distance between the high-voltage and low-voltage pile heads is too small, the high-voltage pile head may be accidentally touched (the high-voltage pile head may be charged), which cannot meet the needs of safe operation. At the same time, some of the existing insulating barriers have a single size, occupy a large space during storage, and are inconvenient to carry and transport. [0003] Based on this, the present invention decides to develop a retractable insulating and isolating baffle, which is used to isolate the high and low voltage pile heads of transformers, so as to achieve the purpose of safe maintenance. Contents of the invention [0004] The purpose of this section is...
