Description

technical field [0001] The present invention relates to the technical field of high and low pressure nuclear phase, in particular to a high and low pressure nuclear phase system and method. Background technique [0002] The load requirements of modern large cities for emergency power supply are 1) flexibility; 2) rapidity; 3) high adaptability; 4) continuity. Therefore, when a power outage occurs, it is necessary to quickly switch the backup power supply to ensure the electricity demand of the city; however, for the newly put into operation or the changed line, the phase and phase sequence must be checked, and the secondary circuit maintenance related to parallel If it has been changed from time to time, the phase and phase sequence must also be checked. If the AC power supplies with different phases or phase sequences are paralleled or closed, a large current will be generated, which will cause damage to the generator or electrical equipment. For correct paralleling, not ...

Problems solved by technology

When the instrument indication of the high-voltage phase nuclear device is close to or zero, the two phases are in the same phase; During the test, it is necessary to switch the line. The traditional way is to switch different bus phases through the hook, which requires frequent operations during live work and faces many safety hazards.

It can be seen that in the case of high-voltage and low-voltage nuclear phases, frequent operations by electric personnel are required, and people exposed to high-voltage environments are likely to cause personal injury. Secondly, the efficiency of nuclear phases is low, and simultaneous verification and detection of three phases cannot be performed.
