Description

Overvoltage protector

Technical Field

The utility model relates to the field of electrical equipment, in particular to an overvoltage protector.

Background

The overvoltage protector is a circuit protection device, which is mainly used for protecting the insulation of electric equipment such as a generator, a transformer, a vacuum switch, a bus, a motor and the like, avoiding damage caused by overvoltage, and can also play a part of the role of a lightning arrester, but is not comparable to the traditional lightning arrester in performance. The most main working principle of the overvoltage is to adopt a mode of dividing the voltage of the zinc oxide valve plate by a discharge gap to reduce operation impact, protect residual voltage and realize the protection of the operation overvoltage, and the product is widely applied to industries such as electric power, chemical industry, coal, construction, electrified railway and the like.

At present, most of the overvoltage protector is fixedly installed in a cabinet or a rack through bolts and the like, the problem that disassembly and assembly are complicated and overhaul efficiency is affected is solved, through searching, the patent with the bulletin number of CN218570039U discloses a compound overvoltage protector for protecting a motor, when the overvoltage protector is installed through the use of a fixing mechanism, a pull rod is pulled to drive a clamping block to move to one side far away from the inside of a mounting plate, a positioning block at the bottom of a shell of the overvoltage protector is spliced in a positioning groove at the top of the mounting plate, the pull plate is loosened, the clamping block is reset under the elastic action of a reset spring, the clamping block is clamped into the inside of a clamping groove arranged at the side surface of the positioning block, the arc groove arranged on the side surface of the clamping block is matched with an arc-shaped protrusion arranged on the clamping groove, the stability of the clamping block and the clamping groove of the positioning block is improved, when the overvoltage protector is disassembled, the pull rod drives the clamping groove on the positioning block to separate the clamping block through pulling the pull plate, so that the limitation of the positioning block is relieved, the overvoltage protector shell is pulled to the outside, the positioning block is separated from the positioning block, and the positioning block is convenient to disassemble for a personnel to maintain the groove wall.

But above-mentioned scheme is in the use, because its arm-tie, the spring, fixture block etc. all have two, and distribute in the both sides of mounting panel, after drawing out the draw-in groove with a fixture block simultaneously, can't fix a position this fixture block, in case loose one's hand, then the fixture block can block into the draw-in groove again under the effect of spring, consequently in actual dismouting in-process, need alone both hands to stimulate two arm-ties simultaneously, make two fixture blocks all break away from the draw-in groove after, another people remove the electric protector casing, make the locating piece break away from the constant head tank, just can take off electric protector by the mounting panel, need two people cooperation operations, and the arm-tie lacks protection and locking, any irrelevant personnel homoenergetic is operated it bare-handedly, there is great drawback.

To this end, we propose an overvoltage protector.
