Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinets, specifically to a front-maintenance structure for a miniaturized capacitor bank. Background Technology

[0002] The original miniaturized capacitor bank circuit breaker mounting plate design was simple, featuring a rear-opening door and removable side panels. However, in some special situations where space is limited, the front door must be opened for maintenance and circuit breaker replacement. Therefore, the circuit breaker mounting plate needs to be improved to allow workers to operate from the front.

[0003] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0004] The purpose of this invention is to provide a miniaturized front-maintenance structure for capacitor banks, so as to overcome the above-mentioned shortcomings and deficiencies of the existing technology.

[0005] A front-maintenance structure for a miniaturized capacitor bank includes: a capacitor bank shell, a communication module, a secondary compartment mounting plate, a circuit breaker mounting plate, and an SVG unit module. The communication module and the secondary compartment mounting plate are connected to the upper part of the capacitor bank shell, the secondary compartment mounting plate is connected to the communication module, the circuit breaker mounting plate is connected to the middle part of the capacitor bank shell, and the SVG unit module is connected to the lower part of the capacitor bank shell.

[0006] The circuit breaker mounting plate is provided with through holes, surge arrester mounting holes, screw mounting holes, wire passage holes, and L-shaped fixed side beams. The through holes are located on the upper and lower sides of the circuit breaker mounting plate, the surge arrester mounting holes are located on the right side of the front of the circuit breaker mounting plate, the screw mounting holes are located on the left and right sides of the circuit breaker mounting plate, the wire passage holes are located on the left and right ends of the lower side of the circuit breaker mounting plate, and the L-shaped fixed side beams are connected to the left and right sides of the circuit breaker mounting plate.

[0007] The beneficial effects of this utility model are:

[0008] Compared with traditional technology, this utility model adds a new type of circuit breaker mounting plate, changing the fixing screw from being driven in from the side of the handheld pistol drill to being driven in vertically, so that it can be disassembled only from the front. Its wire hole is a through structure, so it can be disassembled without first disconnecting the wire. In addition, the front maintenance mounting plate is a modular design of three parts: upper, middle and lower, which facilitates disassembly. Attached image description:

Detailed Implementation

[0013] The present invention will be further described below with reference to specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0014] Example 1

[0015] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a schematic diagram of the circuit breaker mounting plate of this utility model.

[0016] like Figure 1-2 As shown, a front-maintenance structure for a miniaturized capacitor bank includes: a capacitor bank housing 100, a communication module 200, a secondary compartment mounting plate 300, a circuit breaker mounting plate 400, and an SVG unit module 500. The communication module 200 and the secondary compartment mounting plate 300 are connected to the upper part of the capacitor bank housing 100, the secondary compartment mounting plate 300 is connected to the communication module 200, the circuit breaker mounting plate 400 is connected to the middle part of the capacitor bank housing 100, and the SVG unit module 500 is connected to the lower part of the capacitor bank housing 100.

[0017] The circuit breaker mounting plate 400 is provided with a through hole 410, a surge arrester mounting hole 420, a screw mounting hole 430, a wire passage hole 440, and an L-shaped fixed side beam 450. The through hole 410 is located on the upper and lower sides of the circuit breaker mounting plate 400, the surge arrester mounting hole 420 is located on the right side of the front of the circuit breaker mounting plate 400, the screw mounting hole 430 is located on the left and right sides of the circuit breaker mounting plate 400, the wire passage hole 440 is located on the left and right ends of the lower side of the circuit breaker mounting plate 400, and the L-shaped fixed side beam 450 is connected to the left and right sides of the circuit breaker mounting plate 400.

[0018] The principle of this utility model is as follows: The front mounting plate of the capacitor bank enclosure 100 has been changed from a single piece into three parts: an upper part for the communication module 200 and its secondary compartment mounting plate 300, a middle part for the circuit breaker mounting plate 400, and a lower part for the SVG unit module 500. The circuit breaker mounting plate 400, as the core structure in the middle, undertakes the installation of various electrical components. It is designed with functional structures such as through-holes 410, surge arrester mounting holes 420, screw mounting holes 430, cable passage holes 440, and L-shaped fixed side beams 450 to ensure installation flexibility and stability.

[0019] Cable guide holes 410 are located on the upper and lower sides of the circuit breaker mounting plate 400, used for cable and conductor insertion and connection, ensuring convenient and neat electrical connections. Surge arrester mounting holes 420 are located on the right side of the front, facilitating surge arrester installation and optimizing the equipment's lightning protection performance. Screw mounting holes 430 are distributed on the left and right sides, allowing for vertical driving with a hand-held pistol drill. Cable passage holes 440 are located at both lower ends, featuring a through-type structure. Through reasonable layout and connection, the cable passage path is clear, and disassembly can be performed without first disconnecting the wires. L-shaped fixing side beams 450 are located on the left and right sides of the circuit breaker mounting plate 400, providing additional mechanical support and enhancing the overall structural strength. This utility model, by adding a new type of circuit breaker mounting plate, changes the fixing screws from being driven in from the side with a hand-held pistol drill to being driven in vertically, allowing disassembly only from the front. Its through-type cable passage holes eliminate the need for first disconnecting the wires during disassembly, and the front maintenance mounting plate features a modular design in three parts (upper, middle, and lower) for easy disassembly.

[0020] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
