Background technology
The arrester product of 35kV and above is suitable for the places such as transmission line of electricity, substation, industrial and mining enterprises, city
Field demand is big, but its requirement has higher bending resistance tensile property, and arrester of the prior art is fine using glass epoxy
Leading-drawing rod is tieed up as main load component, although device requirement can be met, is limited by objective factors such as tedious process, there are lifes
It is the defects of low yield, operation intensity is big, of high cost, specific as follows：
1st, core load component is mainly epoxy resin fiberglass leading-drawing rod, using screw buckle or jackscrew and upper/lower electrode
Connection, resistor disc are wrapped among more leading-drawing rods, and packaging technology is cumbersome and easily causes loose contact between resistor disc and electrode.
2nd, in insulating coating manufacturing process, core can be acted on by larger external force, and the core bending strength is not high, easily causes
Core damages or eccentric phenomena, influences product quality.
3rd, using epoxy resin fiberglass leading-drawing rod as load component, inevitable requirement silicon rubber skin depth is thicker, causes
Product is clumsy and cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of arrester for being suitable for 35kV and above, using SMC
Layer package core, intensity is high and sealing performance is excellent, can meet double requirements of the product to bending resistance and tension simultaneously, in addition
Production process is simplified, shortens the production cycle, greatly improves production efficiency, stable and reliable product quality.
The purpose of this utility model is achieved through the following technical solutions：
A kind of arrester suitable for 35kV and above, including core, housing, SMC layers, upper terminals, under
Stud and side go out bolt, the core include the top electrode being arranged in order from top to bottom, resistor disc, aluminium bar, insulating ceramic pad and
Lower electrode is enclosed with SMC layers outside the core, and coat suit is external in described SMC layers, and upper terminals connect with the top electrode
It connects, lower stud is connected with the lower electrode, and side goes out bolt and is connected with the aluminium bar.
The SMC layers of upper end is equipped with upper convex portion and is embedded in the top electrode.
The SMC layers of lower end is equipped with lower protrusion and is embedded in the lower electrode.
The full skirt that size is staggeredly spaced is equipped on the outside of the housing.
The advantages of the utility model is with good effect：
1st, the utility model wraps up cores, and the SMC layers of nothing between one-step die casting, with resistor disc using SMC layers
Gap contacts, and intensity is high after shaping, and sealing performance is excellent, while meets double requirements of the product to bending resistance and tension.
2nd, the utility model simplifies production process, shortens the production cycle, greatly improves production efficiency, and product
Stable quality is reliable.
Description of the drawings
