Description
Technical Field
The invention relates to the technical field of power equipment, in particular to a wire clamp.
Background
In the power line, it is often necessary to provide a lightning protection device for preventing damage to the electricity-consuming facilities caused by overvoltage, and when overvoltage occurs, the power supply side should be connected to the ground through the lightning arrester, preferably simultaneously disconnected from the power supply side, and the existing lightning arrester does not have such a function; in this way, the electric equipment is very easy to damage when lightning strike occurs. In addition, there are other cases, such as that the power supply side is connected to two power supply side devices, and when one power supply side device needs to be kept in communication with the power supply side and the other power supply side device needs to be disconnected from the power supply side, there are many types of prior art, such as a knife switch, etc., and for the power line, because of the high position, the ground operator is very difficult to operate, and thus, there is a need for an opening and closing wire clamp that can be operated from the ground.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a wire clamp which can be connected and disconnected with one power-consumption side electrode under the condition of ensuring that the power-supply side electrode and the other power-consumption side electrode are always kept on under the action of external force; the specific technical scheme is as follows:
The pressure-driven type opening and closing line clamp comprises a base, wherein coaxial through holes are formed in two sides of the base, and a power supply side electrode and a power utilization side electrode are embedded into the through holes; a threaded through hole is formed above the base, threads are formed on the outer side of the sliding seat, the sliding seat is screwed in the threaded through hole, and a slideway is arranged in the middle of the sliding seat; one end of the plug-in block is a straight surface, the other end is an inclined surface, the surface corresponding to the power supply side electrode and the plug-in block is a straight surface, and the surface corresponding to the power utilization side electrode and the plug-in block is an inclined surface; the plug-in block is arranged between the power supply side electrode and the power utilization side electrode; a sliding rod is arranged above the plug-in block, the sliding rod is inserted into the slideway, and a spring is sleeved outside the sliding rod; and a force application hole is arranged below the base and corresponds to the plug-in block.
The inclination angle of the inclined plane is 45 degrees.
And a shield is arranged on the outer side of the wire clamp.
The base is cylindrical.
The axis of the force application hole coincides with the axis of the sliding rod.
The invention has the advantages that: the connection and disconnection of the circuit are combined with the application of external force to the electrode on the other side, so that the connection and disconnection of the circuit can be ensured by the action of the external force. When the lightning arrester is used for lightning protection, disconnection from the electricity utilization side can be realized through the action of the upper wiring terminal of the lightning arrester. The connection and disconnection of the circuit can be realized by operating the swing arm on the telegraph pole cross arm through the long rod by a ground person.

Detailed Description
The invention is specifically described below with reference to the accompanying drawings, and as shown in the drawings, the invention comprises a base 1, coaxial through holes are arranged on two sides of the base 1, and a power supply side electrode 2 and a power utilization side electrode 3 are embedded into the through holes; a threaded through hole 7 is formed above the base, threads are formed on the outer side of the sliding seat 6, the sliding seat 6 is screwed in the threaded through hole 7, and a slideway 8 is arranged in the middle of the sliding seat 6; one end of the plug-in block 4 is a straight surface, the other end is an inclined surface, the surface corresponding to the power supply side electrode and the plug-in block is a straight surface 21, and the surface corresponding to the power utilization side electrode and the plug-in block is an inclined surface 31; the plug-in block 4 is arranged between the power supply side electrode 2 and the power utilization side electrode 3; a sliding rod 5 is fixedly arranged above the plug-in block, the sliding rod 5 is inserted into the slideway 8, and a spring 9 is sleeved outside the sliding rod 5; and a force application hole 10 is arranged below the base and corresponds to the plug-in block.
The inclination angle of the inclined plane is 45 degrees.
The outside of the wire clamp is provided with a shield 11.
The base is cylindrical.
The axis of the force application hole coincides with the axis of the sliding rod.
As shown in fig. 4, when the wire clamp is used for a lightning arrester circuit, a stop block 13 made of low-temperature melted alloy is arranged in a lightning arrester shell 12, a baffle 15 is arranged below the stop block 13, an ejecting spring 14 and a zinc oxide resistor piece 18 are arranged below the baffle 15, an upper binding post 16 is fixed above the baffle 15, the lower part of the zinc oxide resistor piece 18 is connected with a lower electrode 17, and the elastic force of the ejecting spring is far greater than that of a spring 9; when a lightning strike occurs, the current melts the stop block 13, the baffle 15 is ejected upwards under the action of the ejecting spring, the upper binding post 16 is driven to move upwards, and the plug-in block 4 is further pressed to move upwards, because the contact surface of the plug-in block and the electrode at the power supply side is a straight surface, the plug-in block is always kept on, and the contact surface of the plug-in block and the electrode at the power utilization side is an inclined surface, so that the plug-in block rises, the plug-in block and the electrode at the power utilization side are disconnected, and in this way, the lightning strike current is conducted with the grounding end through the lightning arrester, and meanwhile, the connection with the power utilization end is disconnected. The wire clamp can also realize the connection and disconnection of a circuit by operating the swing arm on the telegraph pole cross arm through the long rod by ground personnel.
The low-temperature melting alloy is bismuth tin low-melting alloy, and the melting temperature is 150 ℃.
