Description

Technical Field

[0001] The utility model relates to the technical field of compensation controllers and discloses a reactive power compensation controller which is convenient for maintenance. Background Art

[0002] Reactive compensation controller is the core component of reactive compensation device, and it plays a pivotal role. Existing high-end controllers are all based on reactive power for control, but in addition, the design focus is often placed on Chinese character display and data communication. In fact, it is quite complicated to truly achieve perfect reactive compensation control. Achieving perfect reactive compensation control is the main function of reactive compensation controller. Only when the main function is quite perfect can additional functions be considered. Reactive compensation controller has the following characteristics: calculating switching capacitor capacity based on reactive power, high compensation accuracy, high power factor measurement accuracy, wide display range, beautiful LCD display interface, automatic operation and manual operation, real-time display of various parameters of the power grid, etc.

The utility model is provided with a mounting mechanism, and two push plates are used to clamp the left and right sides of the reactive power compensation controller at the same time. When vibration and the like occur during transportation, the spring can play a buffering role, so that the reactive power compensation controller can move slightly, thereby protecting the reactive power compensation controller, overcoming the damage of internal components caused by vibration and the like, and further ensuring the normal operation of the controller.

[0004] However, there are several disadvantages:

[0005] The reactive power compensation controller generates heat during use, and the existing reactive power compensation controller cannot quickly dissipate the heat.

[0006] The reactive power compensation controller is clamped by pushing the push plate with a spring. This method cannot firmly fix the reactive power compensation controller and the reactive power compensation controller may fall off. Utility Model Content
