Description
Technical field
The utility model relates to High-Voltage Electrical Appliances, is specially a kind of disconnecting link Junction box assembly of isolating switch.
Background technology
Isolating switch is to use maximum a kind of electrical equipment in the high-voltage switch electric appliance, is in circuit, to play buffer action.Itself operation principle and relatively simple for structure, but because use amount is big, functional reliability requires high is all bigger to the influence of design, foundation and the safe operation of electric substation, power plant.High voltage isolator be used for branch, close the no load condition circuit, safety is isolated repair apparatus and change-over circuit; And should be able to pass through rated current reliably in running status.Present and the more approaching high voltage isolator of this technology has GW4, GW5 type; Its terminal box part by binding clip, terminal box, conductive shaft, being flexible coupling constitutes; Its operation principle is: terminal box is connected through bolt with leading fulgurite; Being flexible coupling is connected through bolt with terminal box with conductive shaft, and conductive shaft can revolve and turn 90 degrees, and binding clip and conductive shaft clamp through bolt.The terminal box of old structure is an aluminum casting, and this structure through-current capability is little.
The utility model content
The technical problem that the utility model solved is to provide a kind of disconnecting link Junction box assembly of isolating switch, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of disconnecting link Junction box assembly of isolating switch comprises left conductive trough, rainproof cover plate, binding clip, conductive shaft, insulating case, terminal box base, dust cover, soft conducting strip; Said left conductive trough, said terminal box base are to be connected through bolt with said rainproof cover plate; Said left conductive trough, said conductive shaft are to be connected through bolt with said soft conducting strip; Said terminal box base, said conductive shaft, said insulating case, said rainproof cover plate, said binding clip are to connect together through assembling; Said dust cover is to be connected through bolt with said left conductive trough, and left conductive trough adopts the flute profile aluminium section bar.
Beneficial effect
The disconnecting link Junction box assembly of a kind of isolating switch of the utility model connects through bolt, and it is long-pending to have increased conductive contact surfaces, effectively reduces leading electric part resistance, reduces the contact point heating, and through-current capability is strong, and specified dynamic and thermal stability electric current is big.Under the same terms, contact pressure is reliable and stable, thereby it is big to have current-carrying capacity, and electric property is stable, improved the electric reliability of high voltage isolator on the whole, and technology is simple, and is easy to maintenance, and production and maintenance cost are low.
