Abstract
The utility model discloses a release device on the lightning arresters, comprising an insulating housing. The utility model is characterized in that a lower metal wiring terminal is fixed on one end of the insulating housing and electrically connected with a high-voltage end of the arresters; an upper metal wiring terminal is arranged at the other end of the insulating housing and connected with a protected grid system; a conductor is arranged between the lower metal wiring terminal and the upper metal wiring terminal; a magnetic ring for the conductor is arranged inside the insulating housing; a coil is evenly wound on the magnetic ring; two ignition and blasting systems are arranged at two ends of the coil. In case of the occurrence of the arrester fault, high current flows through the conductor, generates voltages effect on the coil to act on the ignition and blasting systems through the electromagnet effect to the magnetic ring, and trigger the ignition and blasting systems under the action of the voltage, so as to explode the release device to release the arrester and the protected grid system, thereby protecting the safety and normal operation of the grid system.
Description
[technical field]
The utility model relates to a kind of release unit, relates in particular to a kind of release unit that is used on the lightning arrester.
[background technology]
In order can when lightning arrester breaks down, in time lightning arrester to be connected with the network system disconnection of being protected, generally on lightning arrester, be placed with release unit.The most release unit that is used on the lightning arrester all is by the high voltage shorted to earth at present, by the electric arc ignition charge that produces, the purpose that the network system that reaches lightning arrester and protected breaks away from, certainly, such release unit has the certain protection effect to lightning arrester and network system, but there is following shortcoming in it: 1, when voltage surpasses a times of lightning arrester working voltage, be easy to take place malfunction, and network system disengaging that will not out of order lightning arrester and protection; 2, when joining, the user can't verify whether product is effective.Be necessary to improve prior art for this reason.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, and a kind of simple in structure, the release unit that can accurately judge the lightning arrester fault is provided.
For achieving the above object, the utility model has adopted following technical proposal:
A kind of release unit that is used on the lightning arrester; include insulation shell; be fixed with the following metal connection end that is connected with lightning arrester at insulation shell one end; the insulation shell other end be fixed be connected with the network system of protecting on the metal connection end; be connected with lead between following metal connection end and the last metal connection end; it is characterized in that: be provided with the magnet ring that passes for described lead in insulation shell inside; be wound with on this magnet ring and can produce faradic coil, this coil is connected with the igniting blasting system that can be lighted by the heat that coil produces.
Aforesaid a kind of release unit that is used on the lightning arrester is characterized in that: described metal connection end down is metal derby or metal lead wire.
Aforesaid a kind of release unit that is used on the lightning arrester is characterized in that: described upward metal connection end is metal derby or metal lead wire.
Aforesaid a kind of release unit that is used on the lightning arrester is characterized in that: described upward metal connection end top is a forked type.
Aforesaid a kind of release unit that is used on the lightning arrester, it is characterized in that: described coil is by the enamelled wire coiled.
Aforesaid a kind of release unit that is used on the lightning arrester is characterized in that: described insulation shell is the one moulding by casting.
The beneficial effects of the utility model are: owing to be provided with the magnet ring that passes for lead in insulation shell inside; on magnet ring, be wound with coil; be connected with the igniting blasting system at the two ends of this coil; therefore when lightning arrester breaks down; lead can flow big electric current; big electric current is by the electromagnetic action to magnet ring; act on the igniting blasting system at generation voltage on the coil; under the effect of voltage, lighted the igniting blasting system; thereby make whole release unit blast; reach the purpose of the network system disengaging of lightning arrester and protection, thereby protected the safety and the normal operation of network system.
[description of drawings]
Be described in further detail below in conjunction with accompanying drawing and execution mode of the present utility model:
Fig. 1 is a sectional structure chart of the present utility model;
Fig. 2 is installed in schematic diagram on the lightning arrester for the utility model;
Fig. 3 is a line principle schematic diagram of the present utility model.
[embodiment]
As Figure 1-3, the utility model is a kind of release unit that is used on the lightning arrester, and it includes insulation shell 1, is fixed with metal connection end 2 down at insulation shell 1 one ends, it can be metal derby or metal lead wire, and this time metal connection end 2 is electrically connected with lightning arrester 8 high-pressure sides; Be fixed with metal connection end 3 at insulation shell 1 other end, it can be metal derby or metal lead wire, and top of metal connection end 3 is a forked type on this so that with being connected of network system.Should go up metal connection end 3 is used for being connected with the network system of being protected; be connected with lead 4 between metal connection end 2 and the last metal connection end 3 down; be provided with the magnet ring 5 that passes for described lead 4 in insulation shell 1 inside; be wound with coil 6 equably on this magnet ring 5, coil 6 is by the enamelled wire coiled in the utility model.Be connected to igniting blasting system 7 at the two ends of this coil 6; when lightning arrester breaks down; lead 4 can flow big electric current; big electric current is by the electromagnetic action to magnet ring 5; act on the igniting blasting system 7 at generation voltage on the coil 6, the fiery broken system of flashpoint under the effect of voltage, thus make whole release unit blast; reach the purpose of the network system disengaging of lightning arrester 8 and protection, thereby protected the safety and normal operation of network system.
