Background technique

When the on-column switch is replaced with load by the bypass method of 10kV distribution network without power outage, the insulation performance of the bypass cable and the access test of the bypass system need to be checked. The cable head is suspended and tested. There is no special auxiliary tool for bypass cable testing. A 10kV distribution network non-power-off operation bypass cable insulation detection auxiliary frame is now developed to achieve the purpose of convenient, safe and accurate detection of bypass cables, so as to ensure the bypass during the 10kV distribution network non-power-off operation with load replacement of the on-column switch. The performance of the cable is good and the operation safety is improved.

SUMMARY OF THE INVENTION

In view of the deficiencies of the prior art, the present invention provides an auxiliary frame for insulation detection of bypass cables for uninterrupted operation of 10kV distribution network. The insulating plate (1) is a rectangular plate with three to five arc-shaped cable head placement slots (2) evenly distributed on the upper part, and two to four connection card slots A (4) at the bottom. ) is provided with a circular ground wire hole (3) on one side, the insulating connection plate (5) is a rectangular plate, and the upper cross is corresponding to the connection card slot A (4) and is provided with four to eight connection card slots B ( 6), the connection slot A (4) at the bottom of the main insulating plate (1) is connected with the connection slot B (6) at the upper part of the insulating connection plate (5), and the main insulating plate (1) is matched and connected. ) is flush with the bottom of the insulating connecting plate (5), and the slot length of the connection slot A (4) is equal to the slot length of the connection slot B (6). The material of the main insulating plate (1) is a new type of insulating material. The material of the insulating connecting plate (5) is a new type of insulating material.

The use method of the present invention: when in use, after the connection card slot A on the main insulating board is connected with the connection card slot B on the insulating connection plate, the bypass cable heads are respectively placed in the cable head placement grooves, and the grounding The wire hole is grounded and then measured.

The beneficial effects of the present invention are: the auxiliary frame for insulation detection of bypass cables during uninterrupted operation of the 10kV distribution network facilitates the detection of personnel, effectively reduces the interference to the detection results, improves the detection accuracy, and ensures that the bypass cables are in operation. The good performance of the process improves the safety during the operation, and provides a strong guarantee for the effective development of the 10kV distribution network without power interruption; at the same time, the 10kV distribution network without interruption operation bypass cable insulation detection auxiliary frame can also be used for poles In the detection of the insulation performance of the tool, the insulation performance during the operation is guaranteed, and the insecurity during the operation is reduced.
