Description

Technical Field

[0001] This invention relates to the field of ring main units, specifically a controller for intelligent ring main units. Background Technology

[0002] A ring main unit is an electrical device consisting of a set of high-voltage switchgear installed in a steel plate metal cabinet or assembled into a modular ring main power supply unit. Its core components use load switches and fuses. It has advantages such as simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. Controllers are usually installed on the side walls of the ring main unit for control purposes.

[0003] Currently, Chinese patent application number CN202123275306.2 discloses a controller for a ring main unit, including a controller housing, an air switch, a live indicator, a short-circuit and ground fault indicator, a selector switch, a digital display, control buttons, an aviation connector, indicator lights, and a pressure plate switch. The digital display, live indicator, short-circuit and ground fault indicator, selector switch, control buttons, indicator lights, and pressure plate switch are fixed to the front of the controller housing, the air switch is fixed to the side of the controller housing, and the aviation connector is fixed to the back of the controller housing.

[0038] This invention provides an improved controller for intelligent ring main units, the working principle of which is as follows;

[0039] First, the design is installed on the intelligent ring network cabinet by fixing plate 32. Then, the controller body 1 is connected to the electrical equipment inside the intelligent ring network cabinet. Then, the user uses the first electric push rod 354 and the second electric push rod 355. Under the action of the first electric push rod 354, the cross rotating frame 353 is located inside the positioning frame 352 and rotated in the longitudinal direction. This causes the sleeve 361 to rotate and tilt in the longitudinal direction through the support block 356, so that the position of the display screen 2 on the controller body 1 is moved to facilitate the observation of the content on the display screen 2. Under the action of the second electric push rod 355, the cross rotating frame 353 drives the support block 356 to rotate in the lateral position, so as to change the lateral rotation position of the controller body 1 for use.

[0040] Second, first move the local / remote switch of the controller body 1 to the local position. The opening and closing operation can be performed by using the lever / button. After manual opening, if there is no power on the cable, the controller body 1 is in the unlocked position. The opening and closing operation of the lever / button and the grounding switch operation can still be performed in the circuit.

[0041] Third, after closing the grounding switch, open the front cover to inspect the cable. If the cable head is still energized after the switch is opened, the interlock switch on the controller will automatically lock. After the interlock key is locked, electric opening and closing and grounding operations can no longer be performed. Manual operation of opening and closing can still be performed by moving the lever. The grounding switch in this bay cannot be closed, and the front cover is locked and cannot be opened.

[0042] Fourth, after the equipment maintenance is completed, move the lock button of the controller body 1 back to the unlock position to perform the opening and closing operation of the lever / button. Then, the local remote switch of the controller body 1 can be moved back to the remote position to enter the system remote control program.

[0043] Fifth, during the use of the controller body 1, the first push rod 343 drives the upright plate 344 to move laterally under the action of the servo motor 342, and the second push rod 345 plays an auxiliary support role for the upright plate 344, thereby causing the frame cover 3631 to move the controller body 1 out.

[0044] Sixth, after the frame cover 3631 is removed, the third electric push rod 3632 is activated. Under the action of the third electric push rod 3632, the sliding rod 3633 is moved. The sliding rod 3633 causes the three first rotating columns 3634 to drive the three baffles 3635 to rotate, so that the top side of the frame cover 3631 is opened, thereby improving the heat dissipation efficiency inside the controller body 1.

[0045] This invention provides an improved controller for intelligent ring main units. By optimizing the support mechanism 3, the controller body 1 can be moved under the action of the pushing structure 34 and the adjusting structure 35. After the controller body 1 retracts into the support mechanism 3, the control buttons are prevented from being directly exposed, thus avoiding accidental touches. Furthermore, the controller body 1 can be adjusted in angle to facilitate observation of the content on the display screen 2 when positioned at a higher position. Additionally, the pushing structure 34 can cause the mounting structure 36 to move the controller body 1 out of the frame 31. After removal, the venting component 363 activates to ensure ventilation. The top side is opened to expand the heat dissipation channel and prevent overheating from damaging the control processing module inside the controller body 1, thereby improving the practicality of the equipment to a certain extent. Inside the frame 31, the upper and lower sides are respectively provided with a first pad 311 and a second pad 312, which support and limit the mounting structure 36. A first slider 37 is provided at the bottom left side of the mounting structure 36, and the bottom side of the first slider 37 contacts and slides against the second pad 312 to provide support. A small support column 38 is provided on the top left side of the mounting structure 36, and the left side of the small support column 38... A second slider 39 is rotatably connected, and its top end is laterally slidably connected to the first pad 311 to provide auxiliary limiting for the mounting structure 36 on the top side. A spring 310 is provided on the bottom right side of the second slider 39, and the other end of the spring 310 is connected to the mounting structure 36. The spring 310 limits the position of the second slider 39, facilitating its return to its original position after rotation. The upright plate 344 is L-shaped, and its bottom side is inserted into the support 346 and slidably connected thereto. The support 346 provides support and limiting for the upright plate 344. The push rod 343 and the second push rod 345 are both composed of two rotating rods connected at one end, so as to extend after rotation; one end of the first rotating column 3634 is inserted into the inside of the baffle 3635 and rotatably connected to it, so that under the action of the sliding rod 3633, the three first rotating columns 3634 respectively drive the three baffles 3635 to rotate, so that the top side of the frame cover 3631 is closed or opened. The middle of the inner side of the baffle 3635 is provided with a second rotating column 3636 that plays a positioning role. The two ends of the second rotating column 3636 are rotatably connected to the frame cover 3631 to ensure the stable rotation of the baffle 3635.
