Fully automatic relay protection tester principle detection equipment. Its design concept is ingenious and original. It can not only adjust the output of two channels separately without interfering with each other; but also combine the two channels into one. The rough and fine adjustments are cleverly combined, which solves the past. The disadvantage of the market positioning problem that cannot be fine-tuned. The distinguishing features of small size, relatively simple operation method, and powerful functions make it not only able to test relatively simple relays (such as voltage, current, intermediate, time, etc.), but also very complex relays (such as differential, Reclosing, various self-holding) can also be used freely, and the operation is convenient. Facts have proved that the ingenious and ingenious structural design of the test box is indeed a powerful assistant for electric power maintenance, debugging, and out-of-work construction workers.

 

       Mainly because the internal products of the relay protection principle detection equipment are partially electronic circuits, which are particularly vulnerable to strong electric field force and electric field strength. The grounding shield of the shell is beneficial to improve the working atmosphere of the relay protection principle detection equipment, and computer maintenance The stability of testing equipment should be improved and maintained by the development of the principle of relay protection. In order to ensure the stability of the detection equipment based on the principle of microcomputer relay protection, it is necessary to suppress the interference source, block the coupling channel, improve the anti-interference ability of the sensitivity circuit, and adopt the automatic detection technology and fault-tolerant structure design to ensure the microcomputer relay protection. The principle tests the stability of the equipment. In order to ensure that the installation of relay protection principle testing equipment stops daily operation.

 

       The daily maintenance and maintenance of the relay protection principle testing equipment should be strictly implemented to cultivate a good habit. Pay attention to the maintenance and cleaning, maintenance and maintenance and power outages after each use: the construction personnel shall stop the relay protection principle testing equipment It is especially necessary to conduct regular inspections and inspections, and make records; do a good job in the finishing work of the detection equipment of the principle of miniature relay protection, and the finishing work must be stopped by two people to avoid accidentally touching the daily operating equipment, and maintain safety with the energized equipment. It is necessary to record the current and voltage sampling values ​​of the relay protection principle testing equipment once a week to prevent personal electric shock and secondary circuit short-circuit and grounding personal accidents, and record the differential current intensity of differential maintenance and maintenance. of.
