Description

A kind of lightning arrester core body of built-in detaching structure
Technical field
This utility model belongs to spark gap technical field, particularly relates to the lightning arrester core body of a kind of built-in detaching structure.
Background technology
Spark gap (surgearrester) is otherwise referred to as overvoltage protection device, overvoltage limiter (surgedivider).Its for protect electrical equipment against high transient overvoltage endanger and limit time of afterflow also often restriction afterflow assignment a kind of electrical equipment.Wherein, some spark gaps need an external disconnector, make itself and system throw away when being used for guaranteeing surge arrester failure.And generally the external disconnector of spark gap is individualism, needs certain adnexa when mounted, both added installation difficulty, improve again cost.
Utility model content
(1) to solve the technical problem that
The technical problems to be solved in the utility model is to provide a kind of spark gap carrying detaching structure in core body.
(2) technical scheme
For solving above-mentioned technical problem, this utility model provides the lightning arrester core body of a kind of built-in detaching structure, and it includes core body overcoat, upper electrode, spring, aluminium flake, resistor disc, sky are assured and bottom electrode;Upper electrode is installed on the top ports of core body overcoat, and bottom electrode is fixedly installed in the bottom port of core body overcoat;Resistor disc is placed in the duct of core body overcoat, and the two ends up and down of this resistor disc connect an aluminium flake respectively;Spring is placed between the bottom of electrode and the aluminium flake on resistor disc top;Sky assures the middle being fixedly sheathed in bottom electrode, and the top that this sky is assured is stretched out the end face of bottom electrode and contacts with the aluminium flake of resistor disc bottom.
Wherein, sky is assured as priming system.
Wherein, upper electrode and bottom electrode all pass through helicitic texture and are connected with core body sleeve thread, and this threaded connection place scribbles D05 fluid sealant.
Wherein, aluminium flake adopts pouring technology to prepare.
Wherein, resistor disc has four, this four sheet resistances sheet from top to bottom successively splicing be welded to connect;This resistor disc is that ZnO material is made.
Wherein, spring is to be made by the steel wire of φ 1.6.
(3) beneficial effect
Compared with prior art, this utility model directly disposes detaching structure in the core body of spark gap so that spark gap carries disconnector function, eliminate the installation of external disconnector, saved installation steps, both dismounted simple and convenient, reduce again production cost, increase economic efficiency;And sky is assured and is fabricated to priming system so that spark gap effectively can depart from system when fault;Wherein, D05 sealant sealing threaded connection place is adopted so that the spark gap sealing effectiveness in threaded connection place reaches preferably both to have prevented threaded connection place from loosening and departs from, and avoids again the thing such as rainwater, dust to enter and causes that the problem of spark gap hydraulic performance decline occurs inside core body;And aluminium flake adopts pouring technology to produce, it is ensured that its premium properties.
