Description

Technical Field

[0001] The invention relates to the technical field of wind power and photovoltaic power generation switch cabinets, in particular to a new energy high-voltage vacuum load switch locking operating mechanism. Background Art

[0002] High-voltage load switch is an electrical appliance with functions between high-voltage circuit breaker and high-voltage isolating switch. High-voltage load switch is often used in series with high-voltage fuse to control power transformer. High-voltage load switch has a simple arc extinguishing device, so it can switch certain load current and overload current. High-voltage vacuum load switch is suitable for frequent operation in switch cabinet. Its arc extinguishing chamber is simpler and smaller in diameter than that of vacuum circuit breaker. The vacuum arc extinguishing chamber is fixed on the isolating knife, and the vacuum break is connected in series with the isolating break. The arc is extinguished by the vacuum interrupter, and the main insulation is borne by the isolating break. When closing, the isolating knife closes the vacuum interrupter and closes quickly. When opening, the vacuum interrupter is disconnected first and then the isolating knife opens. Through the reversing device, the isolating knife continues to move to the grounding position. There are two structures for the coordination of the arc extinguishing break and the isolating break, namely linkage and interlocking. The vacuum load switch operating mechanism refers to a mechanism used to control the connection and disconnection of the vacuum load switch. Its principle is similar to that of a manual knob switch, and the operation of the vacuum load switch is completed through mechanical conversion. As an important component in the power system, the vacuum load switch operating mechanism is mainly used to control the connection and disconnection of the circuit to ensure the normal operation of the power system. When the circuit is short-circuited or overloaded, it can quickly cut off the circuit, thereby protecting power equipment and personal safety. In the prior art, the conventional locking structure is complex and prone to various faults, which affect the normal operation of the equipment.

[0003] A Chinese utility model patent with the authorization number CN216957876U retrieved discloses a new energy high-voltage vacuum load switch locking operating mechanism, including a mounting plate on which an earthing switch operating rod, an isolating switch operating rod and a load switch operating rod are installed, and also includes a panel with an earthing switch operating hole, an isolating switch operating hole and a load switch operating hole, and includes an interlocking plate located between the mounting plate and the panel; a locking assembly is arranged on the upper part of the mounting plate, and when the load switch operating rod is in the closing position, the earthing switch operating rod and the isolating switch operating rod cannot be operated, and when the load switch operating rod is in the opening position, the interlocking plate can move freely up and down and selectively open the earthing operating channel or the isolating operating channel. The operating mechanism provided by the patent is prone to deformation and has an unstable structure, which makes the locking operation ineffective and poses a potential safety hazard.

[0004] Therefore, it is necessary to provide a new energy high-pressure vacuum load switch locking operating mechanism to solve the technical problems raised in the above background technology. Summary of the invention

[0035] Embodiment 3:

[0036] See also Figure 4 In the illustrated embodiment, the power amplifier speaker 3 is provided with evenly distributed honeycomb-shaped air holes, which are electrically connected to the circuit board 16 . An indicator light 8 is fixedly mounted on the upper end of the power amplifier speaker 3 , and the indicator light 8 is electrically connected to the circuit board 16 .

[0037] The lower end of the servo motor 14 is fixedly connected with a shock-absorbing pad 17, which is located at the bottom of the protective shell 1. The shock-absorbing pad 17 is made of elastic materials such as rubber or silicone and is used to absorb vibration when the servo motor 14 is working, reduce noise and protect the equipment.

[0038] In this embodiment, the power amplifier speaker 3 is fixedly mounted on the upper end of the protective shell 1 and is electrically connected to the circuit board 16. The indicator light 8 is fixedly mounted on the upper end of the power amplifier speaker 3 and is electrically connected to the circuit board 16. The protective shell 1 is fixed in the new energy switch cabinet through the support rod 2. The shock-absorbing pad 17 absorbs the vibration generated by the servo motor 14 to slow down the propagation of the amplitude. When the load switch is locked, the pressure spring 11 is deformed by the external force, and the power amplifier speaker 3 and the indicator light 8 warn the surrounding staff, thereby reducing the occurrence of safety hazards caused by the loss of structural parts and effectively improving the stability of the mechanism.

[0039] Embodiment 4:

[0040] During operation, the servo motor 14 receives signals from the wireless module 6, drives the locking rod 5 to open and close through the screw assembly 13, the pressure sensor 12 monitors pressure changes, and sends data to the external control unit through the transceiver 62, and the indicator light 8 provides an intuitive opening and closing status indication.

[0041] In the new energy high-voltage environment, the operating mechanism can withstand high voltage and ensure safety through the flame retardant and insulating properties of the protective shell 1. The wireless module 6 supports multiple wireless communication protocols to ensure reliable transmission of operating instructions.

[0042] The operating principle of the present invention is as follows: when the locking rod 5 drives the limit ring 4 to move downward, making the load switch locking function invalid, the limit ring 4 will simultaneously drive the pressure spring 11 to contract downward. This action causes the signal collected by the pressure sensor 12 to change, and the changed value is transmitted to the remote terminal in real time through the built-in wireless module 6, so as to realize accurate monitoring of the operation process. The power supply module 15 provides stable and environmentally friendly power support for the entire device. The operator can send control instructions through the antenna 7. These instructions are converted into electrical signals by the transceiver 62, and then the noise is removed and the signal strength is amplified by the filter 61, and finally transmitted to the circuit board 16. The circuit board 16 is responsible for parsing these signals and controlling the action of the servo motor 14, thereby driving the movement of the screw assembly 13, causing the locking rod 5 to be displaced, thereby realizing accurate control of the load switch state.

[0043] In order to improve the stability and safety of the system, the present invention specially designs a protective shell 1, which is fixed inside the new energy switch cabinet through a support rod 2 and is provided with a shock-absorbing pad 17 for absorbing the vibration of the servo motor 14 during operation, reducing noise and protecting equipment, and ensuring the long-term stable operation of the system. When the load switch is in a locked state, the pressure spring 11 will be deformed due to external force. At this time, the power amplifier speaker 3 and the indicator light 8 will automatically start, sending a warning signal to the surrounding staff to remind them to pay attention to safety.
