Abstract
The invention relates to an operation tool in an electric-power industry and discloses a U-shaped-bayonet spiral compress grounding wire clamp which is provided with a horizontally arranged U-shaped bayonet mount. The wire clamp is characterized in that a threaded hole is arranged in and a threaded rod is assembled on an upper frame of the horizontally arranged U-shaped bayonet mount; a handle is welded and installed at the upper end of the threaded rod and the lower end of the threaded rod extends into the U-shaped bayonet mount and is connected with a press block. The tail part of the U-shaped bayonet mount is provided with a threaded hole in which a wiring hold-down bolt is assembled. The U-shaped-bayonet spiral compress grounding wire clamp can be rapidly fixed on grounding bodies of different shapes and sizes and the wire clamp is reliable in assembly and connection and not liable to fall off so that a problem that poor contact of the clamp causes overheating burning and brings safety hazards is prevented. The U-shaped-bayonet spiral compress grounding wire clamp is mainly used for power-off maintenance protection grounding of a transformer-substation high-voltage device.
Description
Technical field
The present invention 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; when high voltage device of transformer station interruption maintenance; for preventing that effective control safeguard measure of incoming call is by 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 when the short circuit current, may be burnt because fixture loose contact is overheated, and cannot protect the safety of staff in power failure equipments.So it is vital designing a kind of safe and reliable earthing tool.
Summary of the invention
Object of the present invention is exactly to solve the connection that traditional copper Wiring nose can not adapt to special-shaped earth electrode, and is wound around unreliable, the unsafe problem of earthing mode, and a kind of U-shaped bayonet socket spiral compression earthing clamp is provided.
Concrete scheme of the present invention 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 U-shaped bayonet mount and is connected with a briquetting, has screwed hole be fitted with wiring hold-down bolt at the afterbody of U-shaped bayonet mount.
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 present invention just has deep-slotted chip breaker to screw design.
For guaranteeing working stability, compress reliably, the present invention is provided with vertically arranged guide rail on the madial wall of the horizontally-arranged vertical frame of U-shaped bayonet mount, on briquetting, just Guide Rail Design is had to gathering sill.
And the lower end at screw rod has cannelure, on briquetting, have jack, screw rod is inserted in the jack on briquetting, and on briquetting just the cannelure to screw rod one latch is housed.
Be carved with anti-skid design at briquetting lower surface simultaneously.
Reliable for guaranteeing wiring, the present invention is fitted with elastic washer on wiring hold-down bolt.
For improving intensity, the present invention is provided with reinforcement platform at horizontally-arranged U-shaped bayonet mount upper side frame screwed hole place.
The present invention is simple in structure, 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 fixture loose contact is overheated the security incident of bringing.
