Proper wiring of reactors

2018-04-19 22:24:08

A reactor is a device used to regulate the reactive power distribution of electrical energy in a power system. It usually consists of a coil and an iron core, and there are correct wiring methods to ensure that it works properly. Here are the proper wiring methods for reactors, and two key points to note:

Methods/Steps
1

Coil wiring: Coil terminals of the reactor should be correctly connected according to the requirements of the system. In general, the reactor has three terminals, which are A, B, and C. In A low-voltage system, the A, B, and C terminals of the coil can be connected to the corresponding system phase lines (i.e., phase A, phase B, and phase C). In high-voltage systems, it may be necessary to correctly connect the coil of the reactor according to the three-phase connection mode of the system (such as star or triangle connection).

2

Ground connection: The grounding of the reactor is very important to ensure the safety and stability of the system. In general, the neutral point of the reactor (if any) needs to be grounded. At the same time, the following two points need to be noted when grounding connection:

3

Use an appropriate ground resistance: To limit the flow of the ground fault current, a ground resistance is usually installed at the ground point of the reactor. The value of this grounding resistance should be selected according to the requirements and standards of the system to ensure that the grounding current is within a controllable range. Grounding current monitoring: In order to detect grounding faults in time, a grounding current monitoring device can be installed at the ground point of the reactor. This allows real-time monitoring of changes in the ground current and triggers an alarm or protective action if a set threshold is exceeded.

4

In short, proper wiring and proper grounding are the key steps to ensure the normal operation of the reactor. Connect coil terminals according to system requirements and take proper grounding measures to ensure system safety and stability.
