Description

Technical Field

[0001] This utility model relates to the field of reactive power compensation equipment technology, specifically to an integrated intelligent power capacitor machine. Background Technology

[0002] Existing intelligent power capacitor integrated units typically include a base, a circuit board carrying the main control and signal processing circuits, and a circuit breaker for circuit protection. The current common practice is to directly mount the circuit breaker onto this circuit board; however, this mounting method suffers from significant assembly instability issues in practical applications and long-term operation. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art, thereby providing a securely installed intelligent power capacitor integrated machine.

[0004] Therefore, this utility model provides an integrated intelligent power capacitor, including a capacitor body, a bracket, a circuit breaker, and a circuit board. The capacitor body has multiple terminal assemblies on its top, each terminal assembly including a terminal base and multiple wiring terminals disposed on the terminal base. The bracket is installed on the top of the capacitor body, and the bracket and the capacitor body together form a receiving groove suitable for accommodating multiple terminal assemblies. The bracket has a first mounting block and a second mounting block located in the center of its top surface and arranged opposite to each other, and first positioning blocks located at the four corners of its top surface. The first mounting block and the second mounting block are both inverted L-shaped and face opposite directions. The circuit breaker is installed on the bracket, and movable latching members are provided on both sides of the bottom of the circuit breaker. The latching members have a locking position that engages with the first mounting block or the second mounting block, and an unlocking position that separates from the first mounting block or the second mounting block. The two sides of the circuit breaker abut against the first positioning blocks respectively. The circuit board is installed on one side of the bracket.

[0005] It also includes a cover assembled with the bracket, the cover being formed with an opening for the handle of the circuit breaker to extend out, and a second positioning block located at the edge of the opening, the second positioning block extending toward the interior of the cover and abutting against the side of the circuit breaker.

[0006] The capacitor body has a flange located at its top edge, and the support is formed with a slot for inserting the flange.

[0007] Two network cable interfaces are installed at one end of the cover along its length.

[0008] The terminal block has multiple protrusions, and the wiring terminals are installed inside the protrusions.

[0011] 1. The intelligent power capacitor integrated machine provided by this utility model has an inverted L-shaped first mounting block and a second mounting block forming a bidirectional mechanical lock with the buckle of the circuit breaker. The locking position of the buckle achieves rigid fixation. In addition, the side of the circuit breaker abuts against the first positioning blocks at the four corners of the bracket to form a four-sided limit, which effectively resists the displacement caused by vibration and thermal stress. Compared with the prior art, this installation is more secure.

[0012] 2. The intelligent power capacitor integrated machine provided by this utility model has a second positioning block of the cover abutting against the side of the circuit breaker from the top, forming a bidirectional clamping with the first positioning block of the bracket, further suppressing the shaking of the circuit breaker.
