Description

Technical Field

[0001] This application relates to the technical field of power supply switches, and in particular to a power supply switch. Background Technology

[0002] A power feeder switch is an important device used in power systems to control and protect circuits, especially in low-voltage power grids in mines, where it provides safety assurance for the operation of power supply systems such as coal mines. Power feeder switches typically include electrical components with multiple functions, mainly used to distribute electrical energy, control the on / off state of circuits, and automatically cut off fault current when circuit abnormalities occur.

[0003] In related technologies, a power supply switch includes a housing and a front door. The front door is rotatably connected to the housing. The front door is equipped with a comprehensive protection mechanism, an operating mechanism, and a first power supply mechanism. The housing contains a circuit breaker mechanism and a second power supply mechanism. The second power supply mechanism has a circuit board that is bolted to the housing. The circuit board has various circuit components. The first power supply mechanism is electrically connected to the comprehensive protection mechanism, the operating mechanism, and the circuit breaker mechanism. The second power supply mechanism is electrically connected to the comprehensive protection mechanism, the operating mechanism, and the circuit breaker mechanism.

[0004] With the continuous improvement of circuit breakers, staff need to update the circuit breakers in the feeder switches. Since the circuit breakers are matched with the first power supply mechanism and the second power supply mechanism respectively, staff need to first disconnect the wires on the first power supply mechanism and the second power supply mechanism before they can disconnect the first power supply mechanism and the second power supply mechanism to replace the new equipment. Furthermore, the new equipment needs to be rewired, resulting in many steps in the overall operation and causing considerable trouble for the staff. Utility Model Content

[0005] To address the cumbersome process of replacing the power supply mechanism, this application provides a power supply switch.

[0006] This application provides a power supply switch, which adopts the following technical solution:

[0007] A power supply switch includes a housing and a front door, the front door being rotatably connected to the housing. A circuit breaker mechanism is housed within the housing. A power module is also housed within the housing. The power module includes a fixed housing and a power supply body. The fixed housing is disposed within the housing and has a receiving groove for placing the power supply body. The power supply body is disposed within the fixed housing and electrically connected to the circuit breaker mechanism. A limiting structure is provided on the power module to fix the power module and the housing.

[0008] By adopting the above technical solution, the power module is fixed inside the housing through a limiting structure, and the power supply body is set inside the fixed housing. Compared with traditional power supply switches, the power supply body is integrated into the power module, and the power supply body can be modularly installed, making the internal structure of the power supply switch simpler and the process of installing the power module simpler and more convenient. By integrating the first power mechanism and the second power mechanism into a single power supply body, the wiring of the power module is clearer. Workers only need to disassemble the limiting structure to separate the power module from the housing, saving time for workers to replace the power module. At the same time, workers can work together to assemble the power supply switch step by step, which facilitates the replacement of the power module and improves the work efficiency of workers.

[0009] Optionally, the power module further includes a first base plate, the fixing shell is disposed on the first base plate, the first base plate is provided with a fixing member, the fixing shell is provided with a fixing hole for the fixing member to pass through, and the first base plate is provided with a through hole for the fixing member to pass through; when the fixing member passes through the through hole and is inserted into the fixing hole, the fixing shell and the first base plate are fixed to each other.

[0010] By adopting the above technical solution, the fixing member is inserted into the fixing hole through the through hole, so that the fixing shell and the first base plate can be fixed together. The first base plate can protect the power supply body inside the fixing shell. At the same time, the first base plate can block the opening of the fixing shell to prevent the power supply body inside the fixing shell from falling out of the fixing shell.

[0011] Optionally, the limiting structure includes a limiting strip and a limiting member. The limiting strip is disposed on the housing, and the limiting strip has a receiving hole for the limiting member to be inserted. The first base plate has a limiting hole for the limiting member to be inserted. When the limiting member passes through the limiting hole and is inserted into the receiving hole, the first base plate is fixed to the limiting strip.

[0012] By adopting the above technical solution, the limiting member passes through the limiting hole and is inserted into the receiving hole, so that the first base plate and the limiting strip can be fixed. The staff can first install the power supply body on the first base plate, and then install the first base plate on the limiting strip, which provides convenience for the staff to install the power supply body into the housing.

[0013] Optionally, the limiting hole extends along the width direction of the housing.

[0014] By adopting the above technical solution, when the staff replaces different models of power modules, the size of the first base plate may be different. By extending the limiting hole along the width direction of the shell, the staff can adjust the position of the limiting part in the limiting hole, so that the limiting hole can be adapted to more models of the first base plate.

[0015] Optionally, the circuit breaker mechanism is provided with a second base plate, the second base plate is provided with a locking member, the second base plate is provided with a locking hole for the locking member to be inserted, and the limiting strip is provided with a placement hole for the locking member to be inserted; when the locking member passes through the locking hole and is inserted into the placement hole, the second base plate and the limiting strip are fixed to each other.

[0016] By adopting the above technical solution, when the locking component passes through the locking hole and is inserted into the placement hole, the second base plate and the limiting strip can be fixed to each other. The operator can first install the circuit breaker mechanism on the second base plate, and then install the second base plate on the limiting strip, which makes it convenient for the operator to install the circuit breaker mechanism into the housing.

[0017] Optionally, the limiting strip is provided with a limiting block, and the limiting block is provided with a placement groove for the second base plate to be inserted. The placement groove extends through the width direction of the second base plate. When the second base plate is inserted into the placement groove and the second base plate abuts against the bottom wall of the placement groove, the locking hole is aligned with the placement hole.

[0018] By adopting the above technical solution, the worker inserts the second base plate into the placement groove, so that the second base plate abuts against the bottom wall of the placement groove. At this time, the locking hole is aligned with the placement hole, which makes it easy for the worker to insert the locking part through the locking hole into the placement hole. The worker does not need to spend time aligning the locking hole and the placement hole, thereby saving the worker's time in installing the locking part and improving the worker's work efficiency.

[0019] Optionally, the housing is provided with a manual tripping assembly, which includes a rotating component and a rotating plate. The rotating component is used to drive the rotating plate to rotate. The circuit breaker mechanism is provided with a transmission component, which is used to control the tripping of the circuit breaker mechanism. The transmission component is provided with a fixed plate, which is located on the moving path of the rotating plate. The rotating plate can drive the fixed plate to drive the transmission component to rotate.

[0020] By adopting the above technical solution, when the operator rotates the rotating component, the fixed plate is located on the moving path of the rotating plate, which enables the rotating plate to drive the fixed plate to rotate the conductive component, thereby realizing the tripping of the circuit breaker mechanism. When the feeder switch malfunctions or there is a power outage, the operator can quickly cut off the circuit by manually tripping the switch, ensuring the safe operation of the power system. The manual tripping operation is convenient and not limited by the power supply status, making the operation of the feeder switch safer for the operator.

[0021] Optionally, the housing is provided with a positioning rod, which is located on the moving path of the rotating plate. The positioning rod is used to limit the rotating plate from continuing to rotate. When the rotating plate abuts against the positioning rod, the fixed plate controls the circuit breaker mechanism to open the circuit.

[0022] By adopting the above technical solution, when the rotating plate abuts against the positioning rod, the rotating plate drives the fixed plate to rotate. At this time, the circuit breaker mechanism realizes the tripping. The positioning rod can limit the rotating plate from continuing to rotate, thereby reducing the possibility of damage to other components due to excessive rotation of the limit plate.

[0023] Optionally, the housing has an operating hole for a rotating component to pass through, the rotating component extends out of the outer surface of the housing, and the rotating component rotates circumferentially along the operating hole.

[0024] By adopting the above technical solution, the rotating part rotates around the circumference of the operating hole, which reduces the operating space required for the operator to rotate the manual tripping component, thereby reducing the overall space required for the feeder switch and making it easier for the operator to place the feeder switch.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The power module is fixed inside the housing by a limiting structure, and the power supply body is set inside the fixed housing. Compared with traditional power supply switches, the power supply body is integrated into the power module, and the power supply body can be modularly installed, making the internal structure of the power supply switch simpler and the process of installing the power module simpler and more convenient. By integrating the first power mechanism and the second power mechanism into a single power supply body, the wiring of the power module is clearer. Workers only need to disassemble the limiting structure to separate the power module from the housing, saving time for workers to replace the power module. At the same time, workers can work together to assemble the power supply switch step by step, which facilitates the replacement of the power module and improves the work efficiency of workers.

[0027] 2. By inserting the fastener through the through hole into the fixing hole, the fixing shell and the first base plate can be fixed together. This allows the first base plate to protect the power supply unit inside the fixing shell and to seal the opening of the fixing shell, preventing the power supply unit inside the fixing shell from detaching from the fixing shell.
