Abstract

The utility model relates to an operational tool in a power Industry and discloses a U-shape bayonet spiral compaction ground clamp. The clamp possesses a horizontal U-shape bayonet mount. The clamp is characterized in that an upper frame of the horizontal U-shape bayonet mount is provided with a threaded hole and is configured with a screw; an upper end of the screw is welded with a handle; a lower end of the screw is inserted into the U-shape bayonet mount and is connected with a pressing block; a tail portion of the U-shape bayonet mount is provided with the threaded hole and is configured with wiring compression bolt. The clamp of the utility model can be rapidly fixed on grounding bodies with different shapes. Installation and connection are reliable and the clamp is not easy to drop. A potential safety hazard problem of overheating burning caused by poor contact of the clamp is avoided. The clamp is mainly used for power failure overhauling and protective grounding of high voltage equipment in a transformer substation.

Description

A kind of U-shaped bayonet socket spiral compression earthing clamp
Technical field
The utility model relates to the operation tool in power industry, especially a kind of U-shaped bayonet socket spiral compression earthing clamp.
Background technology
At present in power industry; during the high voltage device of transformer station interruption maintenance; for preventing that effective control safeguard measure of incoming call is with interruption maintenance equipment reliable ground suddenly; traditional copper Wiring nose can only use single bolt to connect; can only take insecure winding earthing mode to the special-shaped earth electrode of non-bolt; this mode may be burnt because the fixture loose contact is overheated when the short circuit current, and can't protect the safety of staff on power failure equipments.So it is vital designing a kind of safe and reliable earthing tool.
Summary of the invention
The purpose of this utility model is exactly to solve the connection that traditional copper Wiring nose can not adapt to special-shaped earth electrode, and earthing mode is unreliable, unsafe problem and be wound around, and a kind of U-shaped bayonet socket spiral compression earthing clamp is provided.
Concrete scheme of the present utility model is: a kind of U-shaped bayonet socket spiral compression earthing clamp, it has horizontally-arranged U-shaped bayonet mount, particularly: have screwed hole, be fitted with screw rod at horizontally-arranged U-shaped bayonet mount upper side frame, the upper end of the screw rod handle that has been welded, the lower end of screw rod puts in and is connected with a briquetting in U-shaped bayonet mount, has screwed hole at the afterbody of U-shaped bayonet mount and is fitted with the wiring hold-down bolt.
For fast and easy is grounded the location of body in U-shaped bayonet mount, the lower frame inner surface at horizontally-arranged U-shaped bayonet mount in the utility model has deep-slotted chip breaker over against screw design.
For guaranteeing working stability, compress reliably, the utility model is provided with vertically arranged guide rail on the madial wall of the horizontally-arranged vertical frame of U-shaped bayonet mount, over against Guide Rail Design, gathering sill is arranged on briquetting.
And the lower end at screw rod has cannelure, has jack on briquetting, and screw rod is inserted in jack on briquetting, and the cannelure over against screw rod is equipped with a latch on briquetting.
Simultaneously be carved with anti-skid design at the briquetting lower surface.
Reliable for guaranteeing wiring, the utility model is fitted with elastic washer on the wiring hold-down bolt.
Be to improve intensity, the utility model is provided with the reinforcement platform at horizontally-arranged U-shaped bayonet mount upper side frame screwed hole place.
The utility model is simple in structure, and is convenient to operation, and the clamping that adapts to various special-shaped earth electrodes connects, and clamping is closely reliable, and difficult drop-off has stopped to burn because the fixture loose contact is overheated the security incident of bringing.
