Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, and in particular to a busbar equipment cabinet. Background Technology

[0002] When switchgear needs maintenance or other operations, reliable grounding is required at points where power may be supplied to prevent electric shock. Current technology typically involves pushing a grounding trolley into the busbar PT cabinet (also called a busbar equipment cabinet or voltage transformer cabinet) for busbar grounding.

[0003] However, when using a grounding trolley with a grounding moving contact for busbar grounding, the busbar PT cabinet isolation trolley needs to be pulled out first, and then the grounding trolley needs to be pushed in so that the grounding moving contact of the grounding trolley is connected to the busbar. Then, the lead wire of the grounding trolley is connected to the switch cabinet shell (ground) to achieve direct short-circuit grounding of the busbar. This busbar grounding method requires enough space to push and pull the trolley, which is difficult to apply to narrow spaces, and the grounding operation is not convenient enough.

[0004] Therefore, it is necessary to develop a busbar equipment cabinet with a small footprint for grounding operation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a busbar equipment cabinet with a small footprint for grounding operation and convenient grounding operation.

[0006] To solve the above-mentioned technical problems, this utility model provides a busbar equipment cabinet, including a busbar equipment cabinet body and a grounding box disposed above the busbar equipment cabinet body. The busbar equipment cabinet body has a busbar compartment, which is connected to the grounding box. The busbar compartment has a first busbar and a second busbar connected to the first busbar. The end of the second busbar has a copper busbar. The grounding box has a grounding switch for controlling the connection and disconnection between the copper busbar and the ground wire, and the grounding box has an operating port for operating the grounding switch.

[0007] As an improvement to the above solution, the grounding box is provided with an extension section extending forward toward the front of the busbar equipment cabinet body, and the operating port is located at the bottom of the extension section.

[0008] As an improvement to the above solution, the grounding box or the busbar equipment cabinet is equipped with a three-phase live display device. The three-phase live display device includes a live indicator light corresponding to the busbar. The grounding box is equipped with a live sensor for sensing whether the second busbar is energized. The live indicator light is connected to the corresponding live sensor.

[0009] As an improvement to the above solution, the operating port is provided with a door panel, the door panel is provided with an electromagnetic lock, and the grounding box is provided with a live sensor for sensing whether the second busbar is energized. The live sensor is connected to the electromagnetic lock to lock the door panel when the live sensor senses that the second busbar is energized.

[0010] As an improvement to the above solution, the three-phase live display device is mounted on the door panel.

[0011] As an improvement to the above scheme, a controller is also included, which controls the grounding switch to prevent it from closing when the energized sensor detects that the second busbar is energized.

[0012] As an improvement to the above solution, the grounding switch includes a push-button type fast grounding switch.

[0013] As an improvement to the above solution, the grounding switch includes a pluggable grounding socket connected to the copper busbar and a pluggable grounding plug connected to the ground wire.

[0014] As an improvement to the above solution, the plug-in grounding socket is connected in parallel with the push-button fast grounding switch.

[0015] As an improvement to the above solution, the grounding box is equipped with a heating dehumidifier and a temperature and humidity control device connected to the heating dehumidifier.

[0016] Implementing this utility model has the following beneficial effects:

[0017] This utility model discloses a busbar equipment cabinet. A grounding box connected to the busbar compartment is set on the top of the busbar equipment cabinet body. A second busbar connected to the first busbar in the busbar compartment is set in the grounding box. A grounding switch for controlling the connection and disconnection of the copper busbar at the end of the second busbar and the ground wire is also provided. The grounding switch can be operated through the operation port on the grounding box to realize the busbar grounding, which reduces the floor space required for equipment grounding and makes wiring operation convenient.

[0018] The grounding box's operating port is located at the bottom of the extended section, making it more convenient to operate;

[0019] The three-phase live display device is connected to the live sensor to indicate whether the bus is energized. The door of the grounding box is locked when the live sensor detects that the bus is energized. At the same time, the controller prevents the grounding switch from closing. This triple protection avoids the situation of the bus being energized and grounded, ensuring high safety.

[0020] When the three-phase live display device shows that the busbar is de-energized, the push-button fast grounding switch can be operated to close. After the push-button fast grounding switch is closed, the plug-in grounding plug can be inserted into the plug-in grounding socket connected to the busbar copper busbar, which further improves the reliability of the busbar grounding.

[0021] Figure 1 This is a schematic diagram of an embodiment of an aggregate feeding system according to the present invention. Detailed Implementation

[0022] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Figure 1 As shown, this utility model discloses an embodiment of a busbar equipment cabinet, including a busbar equipment cabinet body 1 and a grounding box 2 disposed above the busbar equipment cabinet body 1. The busbar equipment cabinet body 1 has a busbar compartment, which is connected to the grounding box 2. The busbar compartment has a first busbar 3. The grounding box 2 has a ground wire and a second busbar 4 connected to the first busbar 3. The end of the second busbar 4 has a copper busbar. The grounding box 2 has a grounding switch for controlling the connection and disconnection between the copper busbar and the ground wire, and the grounding box 2 has an operating port for operating the grounding switch.

[0024] In this embodiment, a grounding box 2 connected to the busbar compartment is installed above the busbar equipment cabinet body 1. A ground wire, a second busbar 4 connected to the first busbar 3 in the busbar compartment, and a grounding switch for controlling the connection and disconnection of the copper busbar at the end of the second busbar 4 with the ground wire are installed in the grounding box 2. The grounding switch can be operated through the operation port on the grounding box 2 to realize the busbar grounding, which reduces the floor space required for equipment grounding and makes the wiring operation convenient.

[0025] To reduce the floor space required when the control panel is fully open and to facilitate operation, the grounding box 2 in this embodiment is provided with an extension section extending forward of the busbar equipment cabinet body 1, and the control panel is located at the bottom of the extension section.

[0026] To further enhance safety, the operating port in this embodiment is equipped with a door panel 21 for sealing. The door panel 21 is equipped with an electromagnetic lock (not shown in the figure). The grounding box 2 contains a energized sensor (not shown in the figure) for detecting whether the second busbar 4 is energized. The energized sensor is connected to the electromagnetic lock to lock the door panel 21 when the energized sensor detects that the second busbar 4 is energized. This door panel 21 is normally closed and can only be unlocked and opened when busbar grounding maintenance is required and the busbar is not energized. When the copper busbar inside the grounding box 2 is energized, the door panel 21 of the grounding box 2 cannot be opened.

[0027] In this embodiment, a three-phase live display device 5 for indicating whether the busbar is energized is preferably provided on the grounding box 2 or the busbar equipment cabinet body 1. Specifically, the three-phase live display device 5 includes a live indicator light corresponding to the busbar, and a live sensor (not shown in the figure) for sensing whether the second busbar 4 is energized is provided in the grounding box 2. The live indicator light is connected to the corresponding live sensor. In this embodiment, the live indicator light and the live sensor are each corresponding to one of the three-phase busbars. The three-phase live display device 5 is preferably installed on the door panel 21 to facilitate determining whether the busbar is de-energized before opening the operation port for grounding operations.

[0028] The busbar equipment cabinet in this embodiment also includes a controller (not shown in the figure). The controller is connected to a live sensor and a grounding switch. When the live sensor detects that the second busbar 4 is energized, the controller prevents the grounding switch from closing, so as to avoid the situation where the busbar is energized and grounded.

[0029] In this embodiment, the three-phase live display device 5 is connected to the live sensor to indicate whether the bus is energized. The door 21 of the grounding box 2 is locked when the live sensor detects that the bus is energized. At the same time, the controller controls the grounding switch to prevent it from closing. This triple protection avoids the situation of the bus being energized and grounded, ensuring high safety.

[0030] The grounding switch includes a push-button fast grounding switch 6, which can only be operated to close the circuit when its three-phase live display device 5 shows that the busbar is de-energized.

[0031] In addition, the grounding switch in this embodiment also includes a quick-plug grounding socket 7 connected to the copper busbar and a quick-plug grounding plug connected to the ground wire. The quick-plug grounding socket 7 is connected in parallel with the push-button quick-plug grounding switch 6. To improve grounding reliability, the quick-plug socket adopts a double-round-hole socket, and the quick-plug plug adopts a double-copper-post plug, enabling two grounding wires to be grounded for each phase busbar. After the push-button quick-plug grounding switch 6 is closed, the quick-plug grounding plug can be inserted into the quick-plug grounding socket 7 connected to the busbar copper busbar, realizing a quick and reliable operation for manually hanging the grounding wire, making the grounding more reliable.

[0032] To further prevent operators from accidentally energizing the busbar when the grounding box 2 is grounded, this embodiment also installs a limit switch (not shown in the figure) on the plug-in grounding socket 7 and the plug-in grounding plug. The limit switch's auxiliary contacts lock the circuit breakers in the busbar incoming switch cabinet and the sectional switch cabinet, preventing the incoming circuit breaker and the sectional circuit breaker from closing when the busbar is grounded, thus avoiding accidental energization during grounding.

[0033] To prevent condensation in the plug-in sockets inside the grounding box 2 from causing discharge accidents, the grounding box 2 in this embodiment is equipped with a heating dehumidifier (not shown in the figure) and a temperature and humidity control device (not shown in the figure) connected to the heating dehumidifier. When the humidity inside the box is high, the intelligent temperature and humidity control device automatically starts the heating dehumidifier to heat and drive away the moisture, thus preventing discharge accidents from occurring inside the grounding box 2.

[0034] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
