Do you know what you should pay attention to in the process of troubleshooting? To keep everyone safe.
(1) Most of the time in the process of handling the fault induction electricity actual operation, so must pay attention to can not cause dc output, communication and ac input short circuit, all kinds of maintenance special tools must do a good job of insulation layer processing, to ensure the safety of life and switch power supply machine equipment power supply safety.
(2) In the actual operation, we should try our best to operate with one hand. In the actual operation, it is not allowed to carry out the maintenance of switching power supply equipment by wearing insulating shoes together with decorations containing metal electric conductors, such as watches, keys and rings.
(3) In the process of dealing with the fault of the switching power supply, the power down must be temporarily reversed to avoid the final power off of the communication power supply system software due to the operation error.
(4) Without knowing the system software of AC and DC power distribution equipment, it is not necessary to turn on or off the ac power supply switch casually or by feeling, and it is not allowed to plug or pull the DC fuse or turn off the DC output leakage protection switch. Avoid further expansion of fault scope.
(5) When using measuring instruments and instrument panel to check the machine and equipment of switching power supply, attention should be paid to the appropriate instructions of the instrument and instrument panel, so as to prevent the destruction of the instrument and instrument panel, or even affect the power supply of the communication power system software to be cut off.
(6) dc output of all kinds of communication power supply system software work basic parameters can consult relevant materials and power consumption equipment of switch power supply, machinery and equipment of the voltage regulation, at the same time, the battery should be fully considered floating current limit, no clear index can't literally set on the spot, in case of accident cause equipment damage and power supply switch power supply.
(7) After the repair of the machine and equipment, it is necessary to clear all kinds of maintenance tools on the spot and in use, and check whether there are other items left in the rack of the machine and equipment of the switching power supply, such as gong wire knife, handle, etc., in order to prevent unnecessary short-circuit accident of the switching power supply.
