Problems solved by technology
At present, the method of using PS15 (or PS20) pin insulators to fix the temporary transition leads has brought the following two disadvantages: First, the working safety distance is small and the risk factor is high
Second, the insulation shielding time is long and the operation efficiency is low
At the same time, pin insulators are fastened by nuts. When wearing insulating gloves, the screwing and fastening process requires more energy for operators
In addition, the temporary transition leads are fixed on the pin insulators by binding wires, which further increases the working time

Embodiment Construction
[0022] In order to better understand the technical solutions of the present invention, the following specific examples are described in detail:
[0023] see figure 1 and figure 2 , a temporary support of the pole top transition lead wire for the live replacement of the 10kV column tie breaker of the present invention includes a bracket and a lead wire clip 3, the bracket fixes the wire clip on the angle steel of the composite cross arm, and the bracket is formed by the bracket base 1 and insulating rod 2.
[0024] see Figure 3 to Figure 5 , the bracket base 1 is embedded with a switch-type magnetic base, its model is SCK-150GSK, its suction force can reach 1500N, which ensures that the bracket can be reliably fixed on the composite cross arm, and the application and release of the magnetic force of the base can be controlled by its switch. , to ensure the convenience of installation and removal process. In order to prevent the magnetic switch from being opened by mistake...

The invention discloses a pole top transition lead temporary support for live replacement of a 10kV pole-mounted interconnecting circuit breaker. The support comprises the support and lead clamps, the support fixes the lead clamp on angle steel of a composite cross arm, the support comprises a support base and an insulating rod, a switch type magnetic base is embedded in the support base, one side of the bottom surface of the support base is provided with a clamping groove matched with the thickness of the horizontal plane of the angle steel, the other side of the bottom surface of the support base is provided with a buckle matched with the height of the vertical plane of the angle steel, and the insulating rod is a T-shaped rod, is arranged on the top surface of the support base and is composed of a vertically-arranged supporting part and a horizontally-arranged isolation part. The two ends of the isolation part are respectively provided with the lead clamps. According to the invention, the operation of conveniently, safely and efficiently replacing the 10kV pole-mounted interconnecting circuit breaker in a live-line manner can be realized.
Description
technical field [0001] The invention relates to a pole-top transition lead temporary support used in the field of electric power engineering for live replacement of a 10kV post-connection circuit breaker. Background technique [0002] The tie circuit breaker plays the role of connecting and separating the front and rear lines in the 10kV distribution line. When the equipment in the front and rear lines fails, it can isolate the fault point through a series of switching operations to reduce the scope of the power outage. When the tie breaker itself fails and needs to be replaced, the scope of the power outage needs to be expanded in the conventional power outage operation, and the front and rear lines are simultaneously outaged, which seriously affects the reliability of the power supply. Therefore, it is particularly necessary to replace the tie-breaker on the 10kV column with electricity. At present, the live replacement of the 10kV pole-mounted tie breaker is divided into...
