Description
Technical Field
The utility model belongs to the technical field of the arrester and specifically relates to a core adopts glass fiber strap to soak winding arrester of resin.
Background
The lightning arrester used on a substation and a power transmission line is divided into a vertical type and a suspension type according to the use condition, is used outdoors, and not only has the characteristics of a complete lightning arrester, but also has excellent weather resistance and mechanical strength (tensile strength and bending strength) so as to prevent the power transmission line and equipment from being damaged by overvoltage, so that the lightning arrester has higher requirements on various characteristics.
In the prior art, the lightning arrester core is formed by vulcanizing SMC at high temperature, then the outside of the core is machined by a lathe, and a layer of weftless tape is wound, so that moisture can easily enter the resistor disc and permeate the resistor disc to cause product damage because the SMC and the weftless tape have certain moisture absorption characteristics. In addition, since the mechanical strength is ensured, the thickness of the SMC is thick, resulting in a thin thickness of the outer silicone rubber, which may result in poor sealing of the upper and lower ends of the arrester and poor weather resistance.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a core adopts soaks resin glass fiber strap winding arrester, has guaranteed mechanical strength, sealing characteristic and the weather resistance characteristic of arrester to inside outside moisture can not permeate the resistance card, promoted product quality.
The purpose of the utility model is realized through the following technical scheme:
the lightning arrester with the core body wound by resin-impregnated glass fiber cloth belts comprises an outer sleeve and the core body, wherein the core body comprises an upper electrode, an insulating pad, an adjusting rod, a resistor disc and a lower electrode, an imine adhesive tape is arranged on the outer side of the core body, and the resin-impregnated glass fiber cloth belts are arranged on the outer side of the imine adhesive tape.
The upper electrode is provided with an upper bolt extending out of the outer sleeve, and the lower electrode is provided with a lower bolt extending out of the outer sleeve.
And the upper part of the outer sleeve is provided with a grounding bolt connected with the adjusting rod.
The outer sleeve is a silicon rubber outer sleeve, the adjusting rod is an aluminum rod, and the resistor disc is a zinc oxide resistor disc.
The utility model discloses an advantage does with positive effect:
1. the utility model discloses the mode change of former SMC suppression core is glass fiber strap resin-impregnated winding mode, and this mode intensity will be higher than SMC core intensity after the core solidification, has guaranteed the mechanical strength of arrester.
2. The utility model discloses the outer winding imine sticky tape of resistance card, then twine the glass fiber strap again and soak the resin, the water absorption rate of core is less than SMC, inside dual assurance outside moisture can not permeate the resistance card, product quality obtained further promotion.
3. The utility model discloses after the change structure, the core diameter diminishes, can make silicon rubber overcoat thickness increase, has ensured the sealing characteristic and the resistant characteristic of waiting of product.
