Technical field
The utility model relates to the lightning arrester that a kind of electrical network uses, and is specifically related to a kind of detachable lightning arrester.
Background technology
Arrester device is a kind of electric equipment indispensable in the operation of power networks, and is in service outstanding apparent important at power distribution network.At present, the lightning arrester that electrical network uses is by the unit of an arrester main body, and high-voltage conducting wires crimping screw and earth lead crimping screw are formed.Adopt direct mounting means, be about to metal oxide arrester directly with moving in the lead access network system, though this direct mounting means also can play the effect that prevents lightning overvoltage, but it must directly be connected on the lightning arrester upper end with lead when mounted, because the used unit of an arrester upper end of 10KV system mostly is screw rod nut press-fit approach, could stablize installation so must install the equipment coil holder additional for thick high-tension bus-bar when mounted.
Because there are many uncertain factors in power distribution network in running, it is inevitable causing lightning arrester to damage, single the direct mounting means of lightning arrester, break down when changing as lightning arrester, then need after the whole line outage, climb up several meters even tens meters high electric poles by the staff high-voltage connection is removed, install, more renew lightning arrester then, therefore, for the continuous operation of electrical network has brought great inconvenience, personnel's labour intensity and the uncertainty of safety have also been increased.
The utility model content
Technical problem to be solved in the utility model provide a kind ofly do not have a power failure, not pole-climbing is replaceable detachable lightning arrester.
For solving the problems of the technologies described above, detachable lightning arrester of the present utility model comprises unit of an arrester, also be provided with composite insulator, the top of composite insulator is provided with upper connecting terminal, upper connecting terminal is connected with upper static contact, upper static contact is connected with last moving contact buckle, the below of composite insulator is provided with lower connecting terminal, lower connecting terminal is connected with the lower carriage that is provided with draw-in groove, the middle part of composite insulator is provided with mounting bracket, the two ends of unit of an arrester are equipped with the aluminium termination, and the aluminium termination of upper end is connected with last movable contact headstock, and last movable contact headstock is connected with last moving contact, last moving contact is connected with last moving contact buckle, last moving contact is provided with the copper sheet that is connected with aluminium termination contact, and the aluminium termination of lower end is connected with the lower moving contact that is provided with semicolumn, and the semicolumn on the lower moving contact places in the draw-in groove on the lower carriage.
The top of described upper static contact and last moving contact buckle is provided with rain cover.
Because technique scheme is by composite insulator, upper end crimping screw, upper connecting terminal (high-pressure side), rain cover, upper static contact, last moving contact buckle, lower carriage, lower connecting terminal (earth terminal), mounting bracket is formed the fixed installation part, by last moving contact, connect copper sheet, the aluminium termination, last movable contact headstock, unit of an arrester, lower moving contact is formed detachable removable parts, therefore, when lightning arrester breaks down in system, change and need not have a power failure, need not take out stitches, do not need personnel's pole-climbing, use a link rod can finish whole lightning arrester and change process, safety, reliably, efficient convenient, for electric power netting safe running and personnel operation bring great convenience.It is the 6-10KV of transformer station outlet and important distribution transforming user's overvoltage protection.
