Abstract

The invention discloses a multi-station insulating rod segmented voltage-withstand testing device. A plurality of grounding electrode bases are arranged on a base, a voltage equalizing ring is fixed through a supporting rod of the base, the voltage equalizing ring is connected with a high-voltage power supply, a testing platform is arranged between the base and the voltage equalizing ring, a plurality of high-voltage output electrodes corresponding to the plurality of grounding electrode bases on the base are arranged on the testing platform, a leakage current collecting device is arranged oneach high-voltage output electrode, each high-voltage output electrode corresponds to one grounding electrode base, the testing platform and the voltage equalizing ring are electrically connected through a high-voltage wire, a plurality of to-be-tested insulating rods can be installed at the same time, the testing platform is driven to move downwards through a lifting device to achieve segmented voltage-withstand test of the insulating rods or voltage-withstand test of different lengths, and the testing data of each to-be-tested insulating rod is collected through each leakage current collecting device; the device is simple in structure and can measure a plurality of to-be-tested insulating rods at the same time, and the measurement of the insulating rods with different heights can be achieved.

Description

technical field [0001] The invention belongs to the field of electric equipment detection, and in particular relates to a multi-station insulating rod segmental withstand voltage testing device. Background technique [0002] The insulating rod is a necessary safety tool for the operation and maintenance of the power system. According to the DL / T1746-2015 "Preventive Test Regulations for Electric Safety Tools", the insulating rod is cycled every 1 year, and it needs to be prevented according to the test method in the above regulations. Sexual trials to test its safety and effectiveness. During the power frequency withstand voltage test, the distance between the two voltage electrodes should be set according to the specified requirements. Since the insulating rod is a tool used in large quantities, the amount of detection once a year is very large. The existing insulating rod testing equipment fixes the voltage electrodes at both ends of the insulating rod. If the length of t...

Problems solved by technology

Since the insulating rod is a tool used in large quantities, the amount of detection once a year is very large. The existing insulating rod testing equipment fixes the pressurized electrodes at both ends of the insulating rod. If it is necessary to change the length of the withstand voltage test of the insulating rod, it must It is inefficient to re-fix the pressurized electrode on an insulating rod, which cannot meet the withstand voltage test for a large number of insulating rods.
