Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a combined switchgear. Background Technology

[0002] Switchgear is a crucial component of power systems. By assembling various electrical equipment within the cabinet, it enables precise control, real-time monitoring, and efficient distribution of power. This not only ensures the stable operation of the power system but also provides comprehensive protection for the internal electrical equipment. The cabinet is constructed from materials with excellent mechanical strength and protective properties, and is assembled from multiple side panels. This structure not only guarantees the overall stability and load-bearing capacity of the cabinet but also effectively provides both protection and isolation. This prevents accidental contact with energized electrical equipment and ensures the cabinet is dustproof and moisture-proof, keeping the internal electrical equipment in a dry and clean environment for extended periods. This ensures the long-term stable operation of the electrical equipment and provides a solid guarantee for the safe and stable operation of the entire power system. To facilitate routine maintenance and repair of the electrical equipment within the cabinet, openings are provided for easy access. To ensure that the protective and isolation effects of these openings are not compromised, cabinet doors are installed at these openings. The cabinet door is installed by hinged to the cabinet body on one side, while the other side is fixed to the cabinet body with a locking device, thus sealing the opening and ensuring the overall protective performance of the cabinet. When maintenance is required, the maintenance personnel only need to release the locking device of the cabinet door and then rotate the door to release the seal at the opening, allowing for convenient and quick maintenance of the switchgear.

[0003] To facilitate rapid emergency circuit breaking in switchgear, a main control switch for the power system is installed inside the switchgear. Disconnecting this switch quickly breaks the power system, meeting emergency response needs. Since the main control switch is located inside the switchgear, the switchgear door must be opened to access and operate it. However, opening the door or directly operating the main control switch poses a high risk of electric shock when a circuit fault occurs, which clearly fails to meet basic safety and reliability requirements. To address this issue, a control mechanism is installed on the switchgear door to disconnect the main control switch. Operating this mechanism allows disconnection without opening the door, significantly reducing the risk of electric shock. However, this design also has a potential drawback: accidentally pressing or rotating the control mechanism could cause it to disconnect the main control switch, resulting in an unnecessary circuit break in the normally operating switchgear and affecting its normal use. Furthermore, to facilitate the installation, commissioning, maintenance, and replacement of various electrical equipment within the switchgear, these devices typically need to be assembled and placed in separate zones. Therefore, adjusting the switchgear's modular structure is crucial. Consequently, the switchgear design has certain shortcomings; it is not only prone to accidental circuit breaks due to accidental contact, but also presents inconveniences in the zoned management of electrical equipment, making it difficult to fully meet the requirements for efficient and safe operation of the power system. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides a combined switch cabinet that prevents circuit breakage caused by misoperation and facilitates the zoned management of power equipment, thereby overcoming the defects in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a combined switch cabinet, including a cabinet body, a partition vertically arranged on one side of the cabinet body, two first cabinet doors arranged on the other side of the cabinet body, and a second cabinet door arranged on the side of the partition away from the first cabinet doors. The second cabinet door and the two first cabinet doors are respectively hinged to the cabinet body by hinges. A fixing seat is embedded in the top of the second cabinet door, and a plug rod is movably fitted inside the fixing seat. A button is provided at the end of the plug rod away from the partition, and a plug block is provided at the other end of the plug rod. A spring is arranged between the plug block and the fixing seat, and the two ends of the spring are respectively installed on the plug block and the fixing seat. The spring is movably fitted... On the plug rod, a master control switch group is installed on the side of the plug block near the partition. The master control switch group is installed inside the cabinet. The fixed base is equipped with an anti-accidental contact mechanism. The anti-accidental contact mechanism includes a fixed ring on the fixed base and a circular block inside the fixed ring. One end of the circular block is installed on the inner wall of the fixed ring. The fixed ring is movably fitted on the plug rod. The side wall of the plug rod is respectively provided with an n-shaped fixed groove and an extension groove. The circular block is movably fitted on the bottom end of one side of the fixed groove. The top end of the fixed groove is located on the side of the bottom end of the fixed groove away from the button. The top end of the extension groove is connected to the bottom end of the other side of the fixed groove.

[0006] Preferably, the master control switch group includes a support base, a normally open push button switch mounted on the support base, a normally closed push button switch mounted above the normally open push button switch, and a relay mounted on one side of the normally closed push button switch. The support base is installed inside the cabinet. The relay, normally closed push button switch, and normally open push button switch are all mounted on the support base. The relay includes a contact switch KM-1 and a coil KM-2 that controls the contact switch KM-1 to close. The normally closed push button switch is connected in series with the contact switch KM-1 of the relay. The normally open push button switch is connected in parallel with the normally closed push button switch and the contact switch KM-1 of the relay. The coil KM-2 of the relay is connected to the normally open push button switch and the normally closed push button switch. The control terminal of the normally closed push button switch faces the plug block. Preferably, a resistor is provided on one side of the relay, the resistor is mounted on the support base, and the relay coil KM-2 is connected in series with the resistor.

[0007] Preferably, the fixing ring is located on the side of the fixing seat away from the partition, one end of the fixing ring is installed on the fixing seat, the fixing seat has a sleeve hole in the middle, the sleeve hole is fitted onto the insert rod, and both sides of the insert rod pass through the sleeve hole respectively. The diameter of the sleeve hole and the inner diameter of the fixing ring are both matched with the diameter of the insert rod. The diameter of the insert block on the side away from the partition and the diameter of the button are not less than the diameter of the sleeve hole. The side of the insert block near the partition is shaped like a frustum, and the diameter of the side of the insert block near the partition gradually decreases along the direction of approaching the partition.

[0008] Preferably, the two sides of the partition are respectively installed on the inner wall of the cabinet, the top of the partition is located at the top of the cabinet, and the bottom of the partition is located at the bottom of the cabinet; a support plate is provided on both sides of the partition, the support plate is installed on the inner wall of the cabinet or on the partition, and a fixing plate is provided on one side of the support plate.

[0009] Preferably, the cabinet body is provided with a cabinet cover on the top of the cabinet body, and the cabinet cover is located above the first cabinet door or the second cabinet door. A first air hole is opened on the top of the side wall of the cabinet body, and the first air hole is located above the first cabinet door or the second cabinet door. A second air hole is opened at the bottom of the cabinet body. A water baffle is provided on the outside of the first air hole and is installed on the outer wall of the cabinet body to prevent rainwater from entering the first air hole. A through hole is opened at the bottom of the cabinet body.

[0010] The beneficial effects of this utility model are as follows: First, the partitions divide the internal cavity of the cabinet, allowing for the separate assembly of multiple electrical devices within the cabinet, thus meeting the needs of assembling multiple electrical devices. The first and second cabinet doors allow for the installation, debugging, maintenance, and replacement of electrical devices from different locations within the cabinet. Furthermore, the fixed base assembles the plug rod, button, plug block, and spring onto the second cabinet door. The control terminal of the master control switch assembly installed inside the cabinet faces the plug block, causing the plug block to move towards the master control switch assembly, thus disengaging the master control switch assembly and rapidly breaking the circuit in the power system. The fixed ring and circular block on the fixed base, along with the fixed groove and extension groove on the plug rod, constrain the movement trajectory of the plug rod. Even if the button is accidentally pressed or rotated, the circular block will restrict the movement or rotation of the plug rod, button, and plug block, preventing accidental button presses from causing a circuit break.

[0011] Secondly, this utility model uses a support base to assemble the relay, normally closed push-button switch, and normally open push-button switch into the cabinet, so that the normally closed push-button switch can be used as a disconnect button and the normally open push-button switch can be used as a start button to control the power supply circuit of the switch cabinet, thereby meeting the control requirements of the power supply circuit. The circuit where the relay coil KM-2 is located is protected by the set resistor.

[0012] Furthermore, this invention features a fixed base with a sleeve hole, allowing the insert rod to move along or rotate within the sleeve hole. The diameter of the side of the insert block away from the partition and the diameter of the button are both not less than the diameter of the sleeve hole, ensuring that both ends of the spring are mounted on the fixed base and the insert block, and preventing the insert rod from slipping out of the sleeve hole. The side of the insert block near the partition is shaped like a frustum, allowing the normally closed push-button switch to be pressed. Moreover, this invention maintains a gap between the partition and the top and bottom of the cabinet, allowing circuitry to pass through the top or bottom of the partition, facilitating the connection of cables to multiple electrical devices mounted inside the cabinet. The fixed plate and support plate securely hold the multiple electrical devices mounted in the cabinet. Attached Figure Description

[0020] like Figures 1 to 7As shown, a combined switch cabinet includes a cabinet body 1. A partition 2 is vertically arranged on one side of the cabinet body 1, and the partition 2 is installed inside the cabinet body 1 to divide the internal cavity of the cabinet body 1, so that multiple electrical devices assembled inside the cabinet body 1 can be assembled in sections, thereby meeting the requirements for assembling and connecting multiple electrical devices. Two first cabinet doors 3 are provided on the other side of the cabinet body 1. A second cabinet door 4 is provided on the side of the partition 2 away from the first cabinet doors 3. The second cabinet door 4 and the two first cabinet doors 3 are respectively hinged to the cabinet body 1. First cabinet slots are opened at both ends of the cabinet body 1, and the two first cabinet doors 3 are respectively hinged to the two ends of the cabinet body 1, with one side of the first cabinet door 3 in contact with the first cabinet slot. To allow electrical equipment to be installed in the inner cavity of the other side of the cabinet 1 through the first cabinet slots opened at both ends of the cabinet 1, a second cabinet slot is opened on one side wall of the cabinet 1. The second cabinet door 4 contacts the second cabinet slot, thereby enabling the installation of electrical equipment in the inner cavity of the other side of the cabinet 1 through the second cabinet slot. A fixing seat 5 is embedded in the top of the second cabinet door 4. A plug rod 6 is movably fitted inside the fixing seat 5. A button 7 is provided at the end of the plug rod 6 away from the partition 2, and a plug block 8 is provided at the other end of the plug rod 6. A spring 9 is provided between the plug block 8 and the fixing seat 5. The two ends of the spring 9 are respectively installed on the plug block 8 and the fixing seat 5. The spring 9 is movably fitted on the plug rod 6. A master control is provided on the side of the plug block 8 near the partition 2. Switch group 10, the main control switch group 10 is installed inside cabinet 1 and is mounted on the power system. The control terminal of the main control switch group 10 faces the plug 8. By controlling the plug 8 to move toward the main control switch group 10, the plug 8 can be used to squeeze the control terminal of the main control switch group 10, thereby disconnecting the main control switch group 10 and controlling the power system to quickly disconnect the circuit. The fixed base 5 is provided with an anti-accidental contact mechanism. The anti-accidental contact mechanism includes a fixed ring 11 on the fixed base 5 and a circular block 12 inside the fixed ring 11. One end of the circular block 12 is installed on the inner wall of the fixed ring 11. The fixed ring 11 is movably fitted onto the plug rod 6. The side walls are respectively provided with an n-shaped fixing groove 13 and an extension groove 14. The round block 12 is movably fitted on the bottom end of one side of the fixing groove 13. The top end of the fixing groove 13 is located on the side of the bottom end of the fixing groove 13 away from the button 7. The top end of the extension groove 14 is connected to the bottom end of the other side of the fixing groove 13. Without external force, the elasticity of the spring 9 is used to apply a force towards the partition 2 to the plug rod 6 and the round block 12, so that the round block 12 is pressed against the bottom end of one side of the fixing groove 13. Therefore, even if the button 7 is not pressed or rotated unintentionally, the round block 12 will restrict the plug rod 6, the button 7 and the plug block 8 from moving or rotating, thereby preventing the circuit from being broken due to accidental pressing of the button 7.When a rapid circuit breaker is needed, first pull button 7 away from partition 2, causing the round block 12 to move to the top of one side of the fixing groove 13. Then, rotate button 7 to move the round block 12 to the top of the other side of the fixing groove 13. Next, press button 7 to move it along the other side of the fixing groove 13 into the extension groove 14, thereby moving the plug 8 and the plug rod 6 toward the control terminal of the master control switch group 10. This allows the plug 8 to press against the control terminal of the master control switch group 10, thus rapidly breaking the circuit. It should be noted that the length of the extension slot 14 is not less than the distance between the plug 8 and the control terminal of the main control switch group 10. After maintenance, if the plug 8 and plug rod 6 need to be reset, simply pull the button 7 to move it away from the partition 2, causing the round block 12 to move to the top of the other side of the fixing slot 13. Then, by rotating the button 7, the round block 12 moves to the top of one side of the fixing slot 13. With the help of the spring 9, the round block 12 is pressed against the bottom of one side of the fixing slot 13, thus completing the reset of the plug 8 and plug rod 6.

[0021] In this embodiment, the master control switch group 10 includes a support base 10-1, a normally open push-button switch 10-2 mounted on the support base 10-1, a normally closed push-button switch 10-3 mounted above the normally open push-button switch 10-2, and a relay 10-4 mounted on one side of the normally closed push-button switch 10-3. The support base 10-1 is installed inside the cabinet 1. The relay 10-4, the normally closed push-button switch 10-3, and the normally open push-button switch 10-2 are all mounted on the support base 10-1 so that the support base 10-1 can be used to hold the relay 10-4 and the normally closed push-button switch 10-3. Switch 10-3 and normally open push-button switch 10-2 are assembled into cabinet 1. Relay 10-4 includes contact switch KM-1 and coil KM-2 to control the closure of contact switch KM-1. Normally closed push-button switch 10-3 is connected in series with contact switch KM-1 of relay 10-4. Normally open push-button switch 10-2 is connected in parallel with normally closed push-button switch 10-3 and contact switch KM-1 of relay 10-4. Coil KM-2 of relay 10-4 is connected to normally open push-button switch 10-2 and normally closed push-button switch 10-3. The control terminal of the normally closed push-button switch 10-3 faces the plug block 8; the main control switch group 10 is mounted on the power supply circuit of the switch cabinet, and the output terminal of the power supply circuit is connected in parallel with the coil KM-2 of the relay 10-4, so that the normally closed push-button switch 10-3 can be used as a disconnect button and the normally open push-button switch 10-2 can be used as a start button to control the power supply circuit; that is, when it is necessary to adjust the power supply circuit from the open circuit state to the start-up state, the normally open push-button switch 10-2 is pressed to close the normally open push-button switch 10-2, so that the power supply circuit can be adjusted from the open circuit state to the start-up state. The output terminal of the power supply circuit and the coil KM-2 of relay 10-4 are powered, thereby using the coil KM-2 of relay 10-4 to attract the contact switch KM-1 of relay 10-4, keeping the contact switch KM-1 of relay 10-4 closed. To this end, the normally open push button switch 10-2 is released. Since both the contact switch KM-1 of relay 10-4 and the normally closed push button switch 10-3 are in the closed state, power is continuously supplied to the output terminal of the power supply circuit and the coil KM-2 of relay 10-4.Conversely, when it is necessary to adjust the power supply circuit from the start-up state to the off state, pressing the normally closed push-button switch 10-3 will disconnect it. Since the normally open push-button switch 10-2 is in the off state when not operated, operating the normally closed push-button switch 10-3 will cause the output terminal of the power supply circuit and the coil KM-2 of the relay 10-4 to be in an open circuit state. If the coil KM-2 of the relay 10-4 is de-energized, it will cause the coil KM-2 of the relay 10-4 to be unable to attract the contact switch KM-1 of the relay 10-4, causing the contact switch KM-1 of the relay 10-4 to switch to the off state. Therefore, after releasing the normally closed push-button switch 10-3, since both the contact switch KM-1 of the relay 10-4 and the normally open push-button switch 10-2 are in the off state, the power supply circuit is adjusted to remain in the off state. Therefore, pressing the normally closed push-button switch 10-3 and the normally open push-button switch 10-2 can quickly control the power supply circuit of the switch cabinet. ;

[0022] Specifically, a resistor 10-5 is provided on one side of the relay 10-4. The resistor 10-5 is mounted on the support base 10-1. The coil KM-2 of the relay 10-4 is connected in series with the resistor 10-5 to protect the relay 10-4. The output terminal of the power supply circuit of the switchgear is connected in parallel with the coil KM-2 of the relay 10-4 and the resistor 10-5. In addition, it should be noted that a circuit breaker S3 is installed on the power supply circuit of the switchgear so that when the power supply circuit is overloaded, the circuit breaker S3 will disconnect to protect the power supply circuit.

[0023] Please see again Figure 3 and 4 The fixing ring 11 is located on the side of the fixing seat 5 away from the partition 2. One end of the fixing ring 11 is installed on the fixing seat 5. The fixing seat 5 has a sleeve hole 15 in the middle. The sleeve hole 15 is fitted onto the insert rod 6. The two sides of the insert rod 6 pass through the sleeve hole 15 respectively. The diameter of the sleeve hole 15 and the inner diameter of the fixing ring 11 are both matched with the diameter of the insert rod 6 so that the insert rod 6 can move along the sleeve hole 15 or rotate in the sleeve hole 15. The diameter of the insert block 8 on the side away from the partition 2 is not less than the diameter of the insert rod 6 so that the two ends of the spring 9 can be installed on the fixing seat 5 and the insert block 8, and the insert rod 6 can be prevented from sliding out of the sleeve hole 15. The side of the insert block 8 near the partition 2 is shaped like a frustum. The diameter of the side of the insert block 8 near the partition 2 gradually decreases along the direction of the partition 2 so that the normally closed push button switch 10-3 can be pressed by using the insert block 8.

[0024] In this embodiment, the two sides of the partition 2 are respectively installed on the inner wall of the cabinet 1. The top of the partition 2 is located at the top of the cabinet 1, and the bottom of the partition 2 is located at the bottom of the cabinet 1, so that there is a gap between the top of the partition 2 and the top of the cabinet 1, and between the bottom of the partition 2 and the bottom of the cabinet 1, so that the cable can pass through the top or bottom of the partition 2, so as to connect the multiple electrical devices assembled in the cabinet 1 using the cable. Support plates 16 are respectively provided on both sides of the partition 2. The support plates 16 are installed on the inner wall of the cabinet 1 or the partition 2. A fixing plate 17 is provided on one side of the support plate 16. The fixing plate 17 is installed on the support plate 16. By installing the multiple electrical devices on the fixing plate 17, the electrical devices are fixed to the cabinet 1.

[0025] Specifically, a cabinet cover 18 is provided on the top of the cabinet body 1. The cabinet cover 18 is installed on the top of the cabinet body 1 and is located above the first cabinet door 3 or the second cabinet door 4. A first vent is provided on the top of the side wall of the cabinet body 1. The first vent is located above the first cabinet door 3 or the second cabinet door 4. A second vent is provided at the bottom of the cabinet body 1. The cabinet body 1 is connected to the outside through the first vent and the second vent to dissipate heat from the cabinet body 1. A water baffle 19 is provided on the outside of the first vent. The water baffle 19 is installed on the outer wall of the cabinet body 1 to prevent rainwater from entering the first vent. A through hole 20 is provided at the bottom of the cabinet body 1. The through hole 20 is used for cables to pass through the cabinet body 1 to meet the wiring requirements of the electrical equipment inside the cabinet body 1.

[0026] The installation method for this product is as follows: (e.g.) Figures 1 to 7 As shown, firstly, the first cabinet door 3 and the second cabinet door 4 are opened sequentially to allow multiple electrical devices to be installed inside the cabinets on both sides of the partition 2 through the first and second cabinet slots opened in the cabinet body 1. Next, the fixing base 5 is embedded in the top of the second cabinet door 4, so that the button 7 is located on the side of the second cabinet door 4 away from the partition 2, and the main control switch group 10 is installed inside the cabinet body 1, controlling the control terminal of the normally open button switch 10-2 to face the plug block 8. Then, the initial installation of multiple electrical devices is completed by installing multiple electrical devices on the support plate 16. Next, multiple electrical devices and the main control switch group 10 are electrically connected sequentially through cables. If it is necessary to connect electrical devices on both sides of the partition 2, the cables need to pass through the top or bottom of the partition 2 to ensure that the electrical connection requirements of the electrical devices are met, thus completing the installation of this product. After that, all wiring is carefully inspected and checked to ensure that each connection is accurate. After verification, a test run is performed to verify the operation of the electrical equipment. Only after the product has passed the test run and met the usage requirements can it be adjusted for formal use.

[0027] The emergency operation method for this product is as follows: First, pull button 7 away from partition 2. This action will move the round block 12 to the top of one side of the fixing groove 13. Next, rotate button 7 to move the round block 12 to the top of the other side of the fixing groove 13. Then, press button 7 to move it along the other side of the fixing groove 13 into the extension groove 14. This will move the plug 8 and the plug rod 6 toward the control terminal of the master control switch group 10, thereby using the plug 8 to press the control terminal of the master control switch group 10 to quickly disconnect the circuit.

[0028] After completing the emergency operation and performing necessary maintenance, the insert block 8 and insert rod 6 need to be reset. First, pull button 7 to move it away from partition 2, so that the round block 12 moves to the top of the other side of the fixing groove 13. Then, by rotating button 7 in the opposite direction, the round block 12 moves back to the top of the side of the fixing groove 13. Then, with the help of the elasticity of spring 9, the round block 12 is pressed against the bottom of the side of the fixing groove 13, thus completing the reset of the insert block 8 and insert rod 6.

[0029] In this embodiment, the inner cavity of the cabinet 1 is divided by the partition 2 so that multiple electrical devices assembled in the cabinet 1 can be assembled in separate areas, thereby meeting the assembly needs of multiple electrical devices. The first cabinet door 3 and the second cabinet door 4 are provided so that the electrical devices in the cabinet 1 can be installed, debugged, repaired and replaced from different positions in the cabinet 1. Furthermore, this utility model uses a fixed base 5 to assemble the plug rod 6, button 7, plug block 8, and spring 9 onto the second cabinet door 4. The control end of the main control switch group 10 assembled inside the cabinet 1 faces the plug block 8, so that the plug block 8 moves toward the main control switch group 10, causing the plug block 8 to squeeze the control end of the main control switch group 10, thereby disconnecting the main control switch group 10 and controlling the power system to quickly disconnect the circuit. The fixed ring 11 and round block 12 set on the fixed base 5, as well as the fixed groove 13 and extension groove 14 opened on the plug rod 6, constrain the movement trajectory of the plug rod 6. Even if the button 7 is accidentally pressed or rotated, the round block 12 will also restrict the plug rod 6, button 7, and plug block 8 from moving or rotating, thereby preventing accidental pressing of the button 7 from causing the circuit to break.

[0030] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
