Description

Technical Field

[0001] The invention relates to the technical field of switch equipment, in particular to a quick plug-in switch cabinet. Background Art

[0002] Switchgear is an important power transmission and distribution equipment in the power system, and is widely used in power generation, transmission, distribution, industrial and mining enterprises, and infrastructure construction. Its main function is to control, protect and detect electrical equipment in the power system, while ensuring the safety and stability of the power transmission process. With the rapid growth of modern power demand and the improvement of energy efficiency requirements, the design and technology of switchgear are also constantly developing, gradually moving towards intelligence, safety and efficiency. There are still the following defects in specific use: 1. Wiring errors may cause short circuits or current overloads, resulting in equipment damage or even fire accidents. This not only endangers the operation of the switchgear, but may also cause serious damage to adjacent equipment and the overall power system. In addition, incorrect wiring may cause arc discharge, resulting in local overheating inside the switchgear, and even explosions or personal injuries, especially in high-voltage environments. Wiring errors may cause the circuit to fail to close normally, causing partial or full system power outages, affecting production activities, living facilities or the operation of critical infrastructure.

[0003] 2. In addition, being stepped on or pulled may cause the outer insulation layer of the power cord to wear or even break, increasing the risk of leakage. Strong pulling may cause the internal conductor to break, resulting in power outage or instability. Damaged insulation or exposed conductors may cause adjacent wires to short-circuit, causing sparks or arcs, and leading to fire accidents. Damaged power cords may increase resistance and cause overheating, further exacerbating fire hazards. Exposed wires can easily cause electric shocks, especially in humid environments.

[0021] The complete working principle and steps of the above embodiment are as follows: Initial qualification: 1. Equipment startup and preparation stage Before powering on the switch cabinet 1, basic inspections need to be completed, including confirmation of external line connections, inspection of grounding devices, resetting of operating handles, etc.

[0022] Check the inner partition 11: The inner partition 11 separates different functional areas, such as the busbar area, circuit breaker area and cable connection area, to ensure the relative independence of electrical components and prevent short circuits or other electrical interference.

[0023] Verification of the air pressure release device: Ensure that the explosion-proof device is in normal working condition to avoid excessive internal air pressure during operation. When the equipment is confirmed to be in good condition, start the main power supply process of the switch cabinet through the operation panel or remote control system; 2. Power transmission stage After startup, the power enters the switch cabinet through the power line and is transmitted to the busbar area, and then distributed to different load ends through circuit breakers, etc.

[0024] Current transmission of busbar: The busbar inside the switch cabinet transmits current to multiple branches. The inner partition 11 plays an isolation role at this time to prevent phase-to-phase short circuit or other electrical accidents.

[0025] Function of the circuit breaker: The circuit breaker automatically closes according to the set current and load requirements to realize the on-off control of electricity. At the same time, the circuit breaker has overload and short-circuit protection functions. Once the current is abnormal, it will immediately trip and cut off the power supply. In this process, the temperature and humidity control device ensures that the internal environment is in a stable state to prevent electrical components from malfunctioning due to excessive temperature or excessive humidity; 3. Monitoring and protection stage The protection relays and sensors in the switch cabinet 1 monitor key parameters such as current, voltage, and temperature in real time to ensure the safe operation of the equipment.

[0026] Monitoring of protection relays: The protection relays will determine the system operating status based on the data from the sensors. For example, when the current exceeds the set value, the protection relay will quickly send a signal to trip the circuit breaker to prevent the equipment from being overloaded and damaged.

[0027] Display function of human-machine interface (HMI): Through HMI, operators can view the operating status of the power system in real time, including current, voltage and other data, and can also receive fault alarm information; 4. Troubleshooting stage During operation, if a fault occurs, such as a short circuit, overcurrent or internal arc, the switch cabinet 1 will activate the automatic protection mechanism: Short circuit protection: When the protection relay senses a short circuit, it quickly sends a signal to disconnect the circuit breaker, cutting off the power supply to prevent the accident from expanding.

[0028] Activation of arc isolation device: If an arc occurs inside, the device will quickly isolate the arc to prevent high temperature and sparks from damaging other components.

[0029] Function of the air pressure release device: When the internal pressure increases, the air pressure release device quickly discharges excess gas to avoid damage to the switch cabinet structure.

[0030] The inner partition 11 plays a key protective role in the fault handling process, limiting the scope of the fault and avoiding spreading to other areas; 5. Load switching and shutdown phase When load switching or shutdown is required, the operator can control the opening and closing of the circuit breaker through the control panel or remote system: Load switching: After the circuit breaker is opened, a load is switched to the backup power supply.

[0031] Shutdown and maintenance preparation: After the operation is completed, the system enters the shutdown state, the power inside the switch cabinet is cut off, and the operator can safely enter for maintenance.

[0032] When using: The synchronous power connection mechanism 2 steps are used to connect the positive, negative and ground electrodes to the terminal port 213 to realize timely power supply when the power line is correctly connected: like Figure 3 to Figure 4As shown, since the negative plug 29, the ground plug 211 and the positive plug 212 correspond to the positive, negative and ground of the terminal port 213 respectively, the operator first wraps the first end of the power cord around the outer wall of the terminal 210 when wiring, and then presses the control switch on the outer wall of the electric telescopic rod 23, the electric telescopic rod 23 starts to extend upward, and then the upward extension of the electric telescopic rod 23 will drive the center buckle 24 fixedly connected at one end thereof to slide in the square groove provided on the outer wall of the external plate 21, so that the sliding of the center buckle 24 will drive the short rod 25 rotatably connected inside thereof to deflect downward, and at the same time, the downward deflection of the short rod 25 will also pull the connecting buckle 26 fixedly connected at one end thereof to the outer wall of the external plate 21 The connecting buckle 26 slides in the square groove opened, and the sliding of the connecting buckle 26 will also pull the long rod 27 connected to one end of the short rod 25 to deflect and move. The deflection movement of the long rod 27 will pull the oblique buckle 28 fixedly connected at one end thereof to slide in the square groove opened in the outer wall of the external plate 21. In this way, when the negative plug 29, the ground plug 211 and the positive plug 212 fixedly connected at one end thereof are respectively moved to the positive, negative and ground positions of the terminal port 213, the positive, negative and ground are connected at this time, and then the positive power line is connected to drive the negative power line and the ground line to be connected to realize power supply, which can reduce wiring errors caused by human operation; The winding and reeling mechanism is used to neatly store the power cord by positioning and reeling. 3 steps: like Figures 5 and 6 As shown, when the electric telescopic rod 23 starts to extend upward, the toothed plate body 31 fixedly connected to its outer wall will drive the gear plate 33 meshing therewith to rotate, and then the annular block 34 fixedly connected to one side of the outer wall will also rotate. When the annular block 34 rotates until the concave-convex surface set on its outer wall contacts the outer wall of one side of the steering rod 35, the concave-convex surface of the outer wall of the annular block 34 will squeeze the steering rod 35 to deflect left and right. Furthermore, the rotation of the gear plate 33 will also drive the vertical toothed plate 39 meshing with each other on its outer wall to rotate, and then the rotation of the vertical toothed plate 39 will drive the horizontal winding column 38 fixedly connected to one side to rotate. At the same time, since the tail end of the power cord is wound around the outer wall of the longitudinal winding column 36, and the power cord surrounds the outer wall of the horizontal winding column 38, the rotation of the horizontal winding column 38 and the left and right deflection of the longitudinal winding column 36 will cause the tail end of the power cord wound around the outer wall of the longitudinal winding column 36 to be evenly rolled up on the outer wall of the horizontal winding column 38. The wave arc starting mechanism is used to guide the arc to propagate stably along a predetermined path. 4 steps: like Figures 7 and 8As shown, when the annular block 34 rotates, the fixed shaft 41 fixedly connected to the outer wall of one side thereof will rotate along with the rotation of the annular block 34, and then the external connecting rod 42 connected to the outer wall of one end of the fixed shaft 41 will deflect and rotate, and the deflection and rotation of the external connecting rod 42 will cause the upper clamping column 43 fixedly connected to one end thereof to push the vertical plate 44 clamped at the outer wall to slide inside the sliding block 45, so that the sliding of the vertical plate 44 inside the sliding block 45 will also drive the lower clamping column 47 clamped at one end thereof to move, so that the movement of the lower clamping column 47 will also The connecting rod 49 and the rotating rod 410 connected to the movable rotation are pulled to contract in the same direction or expand in opposite directions. The contraction or expansion in the same direction of the connecting rod 49 and the rotating rod 410 will also pull the cross rod 412 connected to one end of the cross rod 412 to contract in the same direction or expand in opposite directions. The cross rod 412 moves along a wave-like trajectory inside the trapezoidal plate 46. The current guide needle 48 fixedly connected to the central outer wall of one side of the cross rod 412 will move synchronously with it. Therefore, the movement of the current guide needle 48 will guide the current generated by the arc inside the switch cabinet 1. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
