Abstract
The invention discloses an alternating current withstand voltage test method for a 10kV switch cabinet, which comprises the following steps: before the alternating current withstand voltage test is carried out, firstly removing screws of a cable head, covering a cable with an insulated heat-shrinkable tube cover, and then, carrying out alternating current withstand voltage test operation by a conventional method. As the above technical scheme is adopted, compared with the current test method, the invention relieves the workload of personnel, and the cable head does not need to be pulled out for a certain distance, thereby avoiding fatigue damage of the equipment possibly caused by long-time stress.
Description
Technical field
The present invention relates to a kind of alternating current withstand voltage test method, relate in particular to a kind of alternating current withstand voltage test method of the 10kV of being used for switch cubicle.
Background technology
At present, when the 10KV of transformer station switch outlet cabinet is done AC voltage withstand test to rheology, need to remove the outlet cable end usually and cable end is pulled away from one section safe distance of cable pile crown with guaranteeing insulating requirements, concrete standard is as follows:
| Electric pressure (kV) | Indoor (cm) | Outdoor (cm) |
| ??10KV | ??12.5 | ??20 |
When doing the cabinet type rheology withstand voltage test of switch, cable end need be pulled away from pile crown one segment distance, because the cross-section of cable is very big, deal is very heavy, cause cable to sink, thereby equipment is produced a kind of lower pulling force, make equipment bear pulling force, long-time stressedly may cause the equipment fatigue breakdown, release time is also long simultaneously.
Summary of the invention
Purpose of the present invention provides a kind of alternating current withstand voltage test method of the 10kV of being used for switch cubicle exactly in order to address the above problem.
The object of the present invention is achieved like this:
The invention discloses a kind of alternating current withstand voltage test method of the 10kV of being used for switch cubicle, may further comprise the steps:
Before carrying out AC voltage withstand test, remove the screw of cable end earlier, use isolating shrinkable tube to cover cable, carry out the AC voltage withstand test operation then according to a conventional method.
Described isolating shrinkable tube is cylindrical and the one end adopts polypropylene as end socket.
The material of described isolating shrinkable tube is the insulation synthetic rubber.
The present invention compares with existing test method owing to adopted above technical scheme, has alleviated staff's workload, and need not cable end is pulled out a segment distance, and then avoided the long-time stressed equipment fatigue breakdown that may cause.
Embodiment
The present invention can make specific description by following examples.
Embodiment 1
During the AC voltage withstand test of the rheology in carrying out the 10kV switch cubicle, only need to remove the screw of cable end, adopt isolating shrinkable tube to cover cable, very big distance need not be drawn back and just testing requirements can be satisfied, can't cause the sinking of cable, the lower pulling force that equipment bears cable also reduces thereupon, and the putty of cable can not come loose because of outer the drawing of cable yet.
It is material that isolating shrinkable tube described in the said method adopts 35KV insulation synthetic rubber, makes the long cylinder bodily form, and diameter of section is 80mm, and length is 400mm, adopts polypropylene as end socket.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
Claims (4)
1. alternating current withstand voltage test method that is used for the 10kV switch cubicle may further comprise the steps:
