Before moving the equipment, the on-site debugging personnel must check whether the equipment name is consistent with the equipment name on the operation ticket, and pay attention to the wrong interval and wrong operation and maintenance. In the substation operation, the microcomputer relay protection tester does not allow mobile switch operations Handle, car switch, ground button alarm, alarm bell, return button, trip voltage plate, voltage regulator, voltage switch, etc. When the above equipment needs to be operated due to operation, it must be approved by the relevant operator and operated under the supervision of the operator .


To maintain important equipment, especially the maintenance of complex maintenance or trip circuits, during on-site inspection, there must be approved safety technical measures and test plans, and a dedicated person must be supervised.

The maintenance personnel of the microcomputer relay protection tester must accept and cooperate with the operator when performing the switch transmission test. Otherwise, the relay protection tester personnel must not operate alone. When operating on the maintenance panel and the secondary circuit equipment, they should be close to the two Cover the parts and terminals of the side-running equipment with curtains or insulators marked "in operation" to prevent accidents caused by accidental collisions and gas falling. It is strictly forbidden to drill holes on the operation and maintenance panel. When it is necessary to drill near the operation and maintenance panel When there is a hole or vibration, anti-vibration measures must be taken, and related maintenance should be stopped if necessary.


When the equipment is transported before and after the control panel or the inspection panel or placed above the passage, sufficient intervals should be maintained to prevent the switch from tripping due to the accidental contact of the operation panel. When the equipment is running and part of the maintenance shutdown circuit, except for disconnecting the trip In addition to the pressure plate, the circuit related to the operating equipment not controlled by the trip pressure plate should be disconnected. The bus differential and the fault circuit must be connected. The wiring between the bus differential and the fault circuit must be double open. All broken ends should be encapsulated. And record, and resume recording after running.
