Description

A convenient 10kV drainage clamp

technical field

The utility model belongs to the technical field of a device for live-lapping branch line drainage lines during maintenance of a distribution network.

Background technique

In the indirect operation of the distribution network, the winding method and the clamp method are mostly used in the work of lapping the drain wire. For distribution lines built in high mountains and areas with complex terrain, the insulated arm truck cannot reach the working position, and the operator can only stand on the pole and use the insulated operating pole to indirectly work on the live lap wire. When using the insulation operating rod winding method to lap the drain wire with electricity, the technical requirements for the operators are high, the safety distance is not easy to control, and it is time-consuming and laborious. When the wire clip method is used to connect the drain wire with electricity, the existing wire clip mostly adopts the throat wire clip. The contact surface between the wire clip and the wire is small, and long-term operation may cause heat generation, which has certain safety risks and affects the reliability of power supply and operation safety. .

Contents of the invention

The purpose of this utility model is to solve the above-mentioned problems of the prior art, and to provide a utility model that can be used for live maintenance of distribution networks and adopts indirect operation method to overlap branch line drainage lines. Portable 10kV drainage clamp with high coefficient.

The purpose of this utility model is achieved through the following technical solutions.

A convenient 10kV drainage clamp, including a groove-shaped clamp main body with a hook at one end, a vertical plate at the other end and a longitudinal groove in the middle of the bottom, an auxiliary installation ring installed on the outer end of the hook, and parallel to the clamp Two main line pressure plates on the bottom of the main body groove, two parallel main line fixing bolts that pass through the screw holes on the vertical plate and the front ends are pushed into the main line pressure plate, and the drainage line pressure plate that is horizontally pressed on the bottom line groove of the main body of the wire clamp and The fixing bolt and the locking device installed on the hook mouth; the longitudinal groove at the bottom of the main body of the wire clamp is opened and extended from one end of the vertical plate; the front end of the main wire fixing bolt pushes into the main wire pressing plate and can rotate freely.

When the utility model is used to connect the drain wire with electricity, the drain wire is fixed on the main body of the wire clamp through the drain wire pressure plate and the fixing bolt, and the wire clamp is hooked to the main wire with the aid of the auxiliary installation ring, and the locking device is locked to prevent the wire clamp from falling off , and then push the main line pressing plate through the main line fixing bolt to fix the clamp and drainage line on the main line.

The utility model improves the operation efficiency and safety, and the overall installation is stable, which solves the problems of time-consuming, laborious and difficult control of the safety distance in the existing operation. At the same time, the point contact of the original structure is replaced by the surface contact of the contact surface between the clamp and the wire, which solves the problem that the long-term operation of the existing larynx clamp may cause heat and the like. The utility model realizes the safety and high-efficiency development of the work of lapping the diversion line of the branch line by the indirect operation method for live maintenance of the distribution network, reduces the operation time, reduces the labor intensity of the operators and the probability of risk occurrence during the operation process.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Fig. 1, Fig. 2 and Fig. 3, the utility model includes a grooved wire clamp main body 2 with a hook 2a at one end, a vertical plate 2b at the other end and a longitudinal wire groove 2c in the middle of the bottom, installed outside the hook Auxiliary installation ring at the end 1. Two main line clamps parallel to the bottom of the main line clamp 4. Two parallel main line fixing bolts that pass through the screw holes on the vertical plate and push into the main line clamp at the front end 6. Horizontal press installation The drain line pressure plate and the fixing bolt 5 on the wire groove at the bottom of the main body of the wire clamp, and the locking device 3 installed on the mouth of the hook 2a. The longitudinal groove 2c at the bottom of the main body of the clamp is opened from one end of the vertical plate and extends inward until it is close to the end of the bottom plane. The front end of the main line fixing bolt is pushed into the main line pressing plate and can rotate freely. The main line fixing bolt and the main line pressing plate are connected freely. When the main line fixing bolt rotates and advances forward, the main line pressing plate is pushed forward to move parallelly along the bottom surface of the main line of the pressing plate. without turning.

When adopting the utility model to carry out the work of electrified lap joint drain wire, first insert the drain wire 7 into the longitudinal wire slot 2c, fix the drain wire 7 on the wire clamp main body 2 through the drain wire pressing plate and the fixing bolt 5, and use the auxiliary installation ring 1 to assist Hook the line clamp to the main line, and the locking device 3 pops up to lock the hook to prevent the line clamp from falling off, and then turn the main line fixing bolt 6 to push the main line pressing plate 4 to fix the line clamp and drainage line on the main line.

The utility model is used in the live work maintenance of the distribution network, and the operation steps are as follows:

1) The ground potential operator fixes the measured branch line drainage line through the drainage line pressure plate and the fixing bolt 5 to fix the drainage line 7 in the longitudinal slot 2c of the main body of the line clamp;

2) Then use the gun-type operating lever to lock the auxiliary installation ring 1, and pick the convenient 10kV drainage wire clamp with the drain wire installed to the main line lap position, and the locking device 3 is locked;

3) Finally, another ground potential operator pushes the main line pressing plate 4 with the main line fixing bolt 6 of the insulated operation rotating rod equipped with special tools, and firmly fixes the convenient 10kV drainage line clamp with the installed drainage line to the main line.
