Problems solved by technology

Although the above two methods can reduce economic losses, the power consumption of lower-end users is still affected; from the failure of the isolation switch to the restoration of power supply, certain social impacts and economic losses will still be caused during this period

Embodiment Construction

[0025] Below in conjunction with specific embodiment, the present invention is further described:

[0026] The operating method of the present invention for replacing the 10kV column isolation switch with load is to use an insulated drain wire, use an insulating glove operation method to shunt the live and direct connection at both ends of the column isolation switch, and operate it by a double double bucket truck. The operation of the present invention A total of 5 people are required, including one person in charge (guardian), 2 ground electricians, and 2 electricians in the bucket. The operation steps are described as follows:

[0027] 1) First, set up insulation shielding and isolation measures. After the electricians in the No. 1 and No. 2 buckets are approved by the person in charge of the work, they will operate the insulation bucket trucks respectively and enter the live working area. The insulating bucket should move at a steady and uniform speed. If there is no signi...

Abstract

The invention relates to the field of 10kV pole-mounted disconnectors, in particular to an operation method for on-load replacing of a 10kV pole-mounted disconnector. The operation method is characterized in that insulating current guiding lines are electrifiedly and directly connected, by an insulating glove operation method, to two ends of the pole-mounted disconnector for current shunting, and operations are performed through a double-man double-insulating-bucket-arm truck. Compared with the prior art, the operation method has the advantages that 1) by using the insulating current guiding line current shunting method for on-load replacing of the 10kV pole-mounted disconnector, power supply for lower-end load of equipment can be continued during operation, equipment launching and relanunching can be avoided during on-load operations utilizing an electrified method, operation process is shortened, power supply reliability is improved effectively, and power utilization of users is not influenced during the operation; 2) fault rate of 10kV primary equipment can be reduced greatly, and power supply quality is improved effectively; and 3) by the operation utilizing the double-man double-insulating-bucket-arm truck, operation time is short, few tools are used, energy is saved effectively, and power supply quality is improved.

Description

technical field [0001] The invention relates to the field of 10kV on-column isolation switches, in particular to an operation method for replacing a 10kV on-column isolation switch with a load. Background technique [0002] The isolating switch is generally installed at the lower end of the load switch or on both sides of the tie switch, and is used as the obvious disconnection point of the line. When the on-column isolating switch is located below the load switch, there are two methods used to replace the on-column isolating switch in the past: one is to deactivate the load at the lower end of the isolating switch, and then cut off the power supply at the upper end of the isolating switch by using the method of live disconnection and connecting the lead. The other is to directly deactivate the load switch and replace it after a power failure; when the isolation switch is on both sides of the tie switch, it can only use the ring network to reverse the load to reduce the powe...
