Abstract
The utility model relates to an insert type lightning arrester which belongs to high pressure protecting device. The lightning arrester is characterized in that an upper active contacting tip and a lower active contacting tip are respectively arranged at two ends of the zinc oxide lighting arrester. The lower contacting tip moveably contacts the lower still contacting tip of the falling type fuse and the upper active contacting tip actively contacts with the upper still contacting tip of the falling type fuse. The utility model costs low and has strong applicability. Wire connecting method is simple, and the utility model is easy for operation and maintenance. Insulating rods can be used for installing, dismounting, checking and repairing the utility model, which can save labor, reduce unnecessary power-off and improve the reliability of power supply.
Description
The utility model belongs to High-Voltage Insulation protection equipment, in particular a kind of plug-in lightning arrester.
At present, the 10KV lightning arrester mostly is fixed directly or through the disconnecting link connecting system in the distribution system.Directly the access type wiring is simple, but system must have a power failure during periodical test, many through disconnecting link access type wiring complexity, contact, though can draw back disconnecting link during periodical test carries out, but need install the safety requirements of earth connection when not meeting maintenance, so also require system blackout, influence the power supply reliability of system.
The purpose of this utility model provides that a kind of cost is low, applicability is strong, wiring is simple, the plug-in lightning arrester of easy to operate, easy care, to overcome the defective that prior art exists.
The technical solution of the utility model is achieved in that at the zinc oxide arrester two ends moving contact and lower moving contact is set, lower moving contact contacts with the following fixed contact of fuse switch base is movable, and last moving contact is connected with the upper static contact of fuse switch base.
Good effect of the present utility model is: cost is low, applicability is strong, wiring is simple, easy to operate, easy care, under situation about not having a power failure, with insulating bar can install, demolition, test and overhaul, reduce the amount of labour, reduce unnecessary power failure, improve power supply reliability.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing is a structural representation of the present utility model.
With reference to accompanying drawing, the 1st, zinc oxide arrester, be welded with lower moving contact 2 and last moving contact 9 at the two ends of zinc oxide arrester 1, lower moving contact 2 contacts with the following fixed contact 3 formation activities of fuse switch base, and last moving contact 9 is inserted in the upper static contact 8 of fuse switch base, which is provided with the draw ring 10 that makes things convenient for the lightning arrester plug, the 4th, the lower connecting terminal on the fuse switch base, the 5th, connecting plate, the 6th, insulator, the 7th, the upper connecting terminal of fuse switch base.
The course of work of the utility model plug-in lightning arrester is: upper connecting terminal is connected on the high-tension line, and lower connecting terminal is connected with the earth, and connecting plate is fixed on the cross-arm.When the overvoltage of high pressure thunderbolt exists; valve block conduction in the zinc oxide arrester; pass to down fixed contact 3 through lower moving contact 2, last, constitute shorted to earth through lower connecting terminal 4; play the effect of protection electric equipment; if desired lightning arrester is tested and keeped in repair, last moving contact 9 is extracted by draw ring 10 with insulating bar, the other end is thrown off naturally; demolition is very convenient, and need not have a power failure.
