Description

Technical Field

[0001] The utility model relates to the technical field of power transmission and transformation and circuit maintenance, and in particular to a wire clamp plate for anti-dropping power distribution equipment. Background Art

[0002] A wire clamp is a component commonly used to connect and fix wires. It is usually made of metal and is widely used in wires and cables, electronic equipment, electrical construction and other fields. It can provide stable connection and conduction, prevent the wires from loosening or disconnecting, and ensure the normal operation of the circuit. Figure 1 As shown, it is composed of a base plate 7, a pressure plate 8 and a wire clamp bolt 9. The pressure plate 8 of the wire clamp is an arched structure. A groove is provided on the base plate 7 at a position corresponding to the arched structure of the pressure plate 8. The groove of the base plate 7 forms a bulge on the back. The groove of the base plate 7 and the bulge of the arched structure of the pressure plate 8 form a gap for accommodating the wire. The pressure plate 8 is fixed to the base plate 7 by the wire clamp bolt 9. The wire is clamped between the base plate 7 and the pressure plate 8 to achieve good contact.

[0003] With the continuous growth of the country's demand for electricity and the development of the power grid system, the continuous increase in the capacity of the power grid system has become an important issue. At the same time, the power supply load continues to grow, and the system operating current is also getting larger and larger, which leads to an increase in the current carried by the outlet terminals of electrical equipment. Wires are usually connected and fixed by wire clamps. As the current increases, the wire clamps will face higher current density and temperature rise. The main reason for the heating failure of the wire clamp is that the contact surface of the wire clamp is loose, corroded, oxidized or contaminated, which will increase the contact impedance, thereby generating additional resistance when the current passes through the wire clamp, which in turn causes the wire clamp to heat up. Therefore, it is necessary to regularly inspect and maintain the line, replace or tighten the wire clamp bolts, and ensure good contact between the wire and the wire clamp.

[0004] The traditional installation and tightening of wire clamps requires two people to complete. One person uses a wrench to fix the bolts on the back of the wire clamp, and the other person tightens or removes the nuts. Due to the limited working surface of the high-altitude operation, the tightening of the wire clamp is difficult to implement, the work intensity is high, time-consuming and laborious, and it is difficult for two people to accurately cooperate to ensure the consistency of the pressure of the wire clamp, and the maintenance work effect is not good. The existing installation and tightening of wire clamps uses a wire clamp splint, which is placed under the bottom plate of the wire clamp and positioned by a positioning module. The bolt head of the wire clamp bolt falls into the plate groove and is clamped. A locking structure is set on one end of the positioning module. The wire clamp is clamped by the locking structure. One person can complete the tightening or removal of the wire clamp, which can reduce the intensity of the installation and maintenance of the power distribution equipment and improve work efficiency. However, the bolt head of the wire clamp bolt will have the problem of unreliable limit in the plate groove, and the clamp fixation will be loose through the locking structure at one end, which will cause the splint to fall and cause safety hazards.

[0008] Furthermore, a groove for accommodating the protrusion of the wire clamp is formed on the limiting ridge, and the wire clamp is positioned on the clamp plate. The protrusion formed on the back of the groove of the wire clamp base plate is located in the groove, and positioning modules are provided on both sides of the groove.
