Abstract
The invention provides a lightning arrester test auxiliary device, which belongs to the technical field of lightning arrester test. The lightning arrester test auxiliary device includes a test box anda panel arranged in the test box. The panel includes an upper board, a lower board, and a plurality of sleeves arranged between the upper board and the lower board. A movable spring is arranged in each sleeve. Grounding terminals connected with the springs are arranged at the bottom of the box body of the test box. Screws at the lower end of a lightning arrester pass through the sleeves and are electrically connected with the springs. The lightning arrester test auxiliary device is applicable to a 10kV lightning arrester removed from a metal structure or a switch cabinet. Multiple lightning arresters can be placed on the auxiliary device, and the auxiliary device can be pulled to a test site for test. The lightning arrester test auxiliary device has the characteristics of being flexible to carry, convenient to operate, and reliable and practical. In the prior art, the test equipment needs to be carried to multiple places for the test of a large number of lightning arresters, which results in complex test and lower test efficiency. The technical problem is solved by using the lightning arrester test auxiliary device of the invention.
Description
technical field [0001] The invention belongs to the technical field of lightning arrester testing, and more specifically relates to a lightning arrester testing auxiliary device. Background technique [0002] In electric power maintenance, the electrical test team is responsible for monitoring and diagnosing the operating status of power equipment, which requires the electrical test team to be able to quickly and accurately obtain test data and judge the operating status of the equipment. Among them, the arrester test occupies a large part of the entire work of the electrical test team. [0003] In the routine test, the arrester test is mainly the measurement of the arrester DC 1mA voltage (U1mA) and the leakage current at 0.75U1mA. U1mA is the voltage value at both ends of the tested arrester when the gapless metal oxide arrester passes a 1mA DC current. Measuring the U1mA of the zinc oxide arrester is mainly to check whether the valve plate is damp and aging, and to dete...
