The wiring method of the circuit breaker has the front of the board, the back of the board, the plug-in type, the drawer type, if the user has no special requirements, they are supplied according to the front of the board, and the wiring before the board is a common wiring method.
1. Wiring method behind the board: The wiring behind the board is characterized by replacing or repairing the circuit breaker, without wiring from the beginning, only disconnecting the pre-power supply. Because the structure is special, the product has been equipped with special equipment boards and equipment screws and wiring screws according to the planning requirements when leaving the factory, and special attention is paid to the fact that the reliability of the touch of the large-capacity circuit breaker will directly affect the normal use of the circuit breaker, so it is necessary to pay attention to the equipment and strictly follow the requirements of the manufacturer.
2. Plug-in wiring: On the equipment board of the complete set of equipment, first equipment a circuit breaker equipment base, 6 plugs on the equipment base, and 6 sockets on the connection board of the circuit breaker. There is an adapter plate on the surface of the equipment base or there are bolts behind the equipment base, and the power line and load line are connected to the equipment base in advance. When in use, plug the circuit breaker directly into the device base. If the circuit breaker is broken, just pull out the broken one and replace it with a good one. It has a shorter replacement time than the front and back wiring of the board, and it is convenient. Because plugging and unplugging requires manpower. Therefore, the shell current of China's plug-in products is limited to 400A. This saves time for repairs and replacements. Plug-in circuit breakers should check whether the plug of the circuit breaker is compressed when the equipment is installed, and the circuit breaker should be tightened safely to reduce touch resistance and improve reliability.
3. Drawer wiring: The inlet and outlet drawers of the circuit breaker are rolled clockwise or counterclockwise by the rocker, which is used in both the main circuit and the secondary circuit
The plug-in structure eliminates all the necessary isolators of the fixed type, achieves a dual-purpose machine, improves the economy of use, brings great convenience to operation and maintenance, and increases safety and reliability. In particular, the main circuit contact holder of the drawer holder can be used in common with the contact holder of the NT type fuse.

DC reactor for inverter and design calculation - LS power generation
The DC reactor for the inverter is also called the flat wave reactor, which is connected in series in the DC bus (terminals P1 and P+). The main thing is to reduce the higher harmonic component of the input current and improve the power factor of the input power supply (to 0.95). This reactor can be used at the same time as the AC reactor, and the inverter has high power ...

Grounding of the secondary side of the voltage transformer and the current transformer - power generation
1. The transformer is grounded twice
It refers to the grounding of the S2 terminal of the current transformer or the ground of the n terminal of the voltage transformer. As long as the single point is grounded, because the transformer is blocked between the second and the first, before grounding, the secondary winding has no potential connection with the ground, after grounding, the transformer ...
