Operating procedures for operation of distribution cabinet

  The power distribution cabinet shall comprehensively monitor the voltage, current, frequency, useful power, useless power, electric energy, harmonic and other power quality
Users can see the operation status of the distribution cabinet system at a glance, so as to find potential safety hazards and avoid risks as soon as possible Distribution cabinet is an electrical product used for power generation, transmission, distribution, electric energy conversion and consumption in the power system to play the role of on-off, control or protection
The voltage level is 3
6kv~550kv
It mainly includes high-voltage circuit breaker, high-voltage disconnector and grounding switch, high-voltage load switch, high-voltage automatic reclosing and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof distribution cabinet device and high-voltage distribution cabinet
During normal operation of the distribution cabinet, the circuit can be switched on or off mainly by means of manual or automatic switches, and when it fails or operates abnormally, it will also cut off the circuit or give an alarm by means of protective appliances
It is a total circuit distribution cabinet for all users
In principle, the distribution box, distribution cabinet and power cabinet mentioned by people are the same thing, but they are different in terms of terms and appearance
Generally, the distribution cabinet is relatively small and hung on the wall, while the other two are three-dimensional The power distribution cabinet is the power distribution center of the ship and the normal operation of equipment
No irrelevant person is allowed to pull the switch on the board
After the generator set is started, it shall be manually and slowly accelerated by using the speed up switch of the power panel until the generator enters the normal working state and the voltage and frequency reach the specified value, and then it can be closed for power transmission
After the distribution board enters the power distribution state, it is not allowed to pull the speed up switch of the power panel at will
The locking switch of the air circuit breaker shall not be used in non emergency situations
The parallel operation of generator shall be carried out in strict accordance with the requirements and regulations of paralleling conditions, and attention shall be paid to reverse power (reverse current) and paralleling failure
During shutdown, the generator load shall be cut off first, and then the no-load shutdown shall be conducted
Direct shutdown with load is not allowed
When the shore power is interleaved, the power switches of the shore power panel shall be cut off first, and then the correctness of the wiring and phase sequence shall be checked
After confirmation, the ship shore power can be converted
It is strictly prohibited to take charge of the operation
The distribution cabinet shall be cleaned and maintained regularly to keep the equipment in good working condition
