Description

Technical Field

[0001] The present application relates to the technical field of electrical cabinets, and in particular to a node cabinet. Background Art

[0002] The node cabinet is a comprehensive equipment designed to meet the needs of substation automation, telecontrol, telemetering, telesignaling, protection and direct power supply to three-phase AC motors.

[0003] In the related art, a node cabinet usually includes a cabinet body and a cabinet door. A locking structure for controlling the opening and closing of the cabinet door, a control panel for operating the locking component, and a group of electrical switch components for controlling the circuit are installed inside the cabinet body. When the staff temporarily take electricity, in order to ensure the safety of the staff, the locking structure will unlock the cabinet door only by operating the internal electrical switch component through the control panel so that the electrical switch component inside the cabinet meets the two conditions of grounding and disconnection at the same time.

[0004] However, the State Grid currently requires that two sets of electrical switch assemblies be made inside a node cabinet. Another installation cavity and a protective door for sealing the installation cavity are provided on the other side of the cabinet body away from the cabinet door. The protective door and the original cabinet door are not on the same side. However, when external cables need to be connected to the second set of electrical switch assemblies for temporary power supply, the second set of electrical switch assemblies are also required to meet the two conditions of grounding and disconnection at the same time. However, the original locking structure cannot simultaneously interlock the grounding and disconnection of the two sets of electrical switch assemblies, and there is room for improvement.

[0006] A node cabinet provided in this application adopts the following technical solution:

[0007] A node cabinet comprises a cabinet body, wherein a control cavity, a first electrical component located in the control cavity and a second electrical component located in the control cavity are provided on the side of the cabinet body; a first wiring cavity and a second wiring cavity are provided on two opposite sides of the cabinet body respectively, a first wiring head connected to the first electrical component is provided in the first wiring cavity, and a second wiring head connected to the second electrical component is provided inside the second wiring cavity; a first box door and a first locking piece for locking the first box door are provided at the opening of the first wiring cavity, a second box door and a lock core arranged on the second box door are provided at the opening of the second wiring cavity, a lock key for unlocking the lock core is provided on the side of the control panel, and a second lock core for locking the lock key is provided inside the control cavity; a first control component linked with the first electrical component and used to control the first locking piece, and a second control component linked with the second electrical component and used to control the second locking piece are provided inside the control cavity; a control panel for controlling the first electrical component, the second electrical component, the first control component and the second control component is provided at the opening edge of the control cavity.

The staff can give instructions to the first limit member and the second limit member through the control panel to make the second control component in the open and grounded state. The first limit member and the second limit member will release the limit on the locking plate, so that the locking plate can move up and down under the action of the reset member, so that the axis of the locking rod coincides with the axis of the locking hole, which is convenient for the subsequent rotation of the lock key to insert the locking rod into the locking hole on the locking plate to unlock the lock key; when the second box door is opened to temporarily take power, the second control component is in the open and grounded state at the same time, so as to ensure the safety performance when taking power.

[0011] Optionally, the first limiting member includes a first rotating shaft linked to the grounding operation and a limiting wheel fixed on the rotating shaft, and a limiting plate for limiting the side surface of the locking plate is provided on the outer periphery of the limiting wheel.

[0012] By adopting the above technical solution, the control panel controls the second electrical component through the first control component to rotate the first rotating shaft and the limiting wheel when adjusting from the grounded state to the ungrounded state; when the second electrical component is in the grounded state, the limiting plate presses against the upper side surface of the locking plate, so that the locking plate cannot move upward; when in the ungrounded state, the first rotating shaft rotates, and the limiting plate releases the abutment limit on the upper part of the locking plate. When the lower part of the locking plate is also unlocked, the locking plate can move up to a position that presses against the outer periphery of the limiting wheel, thereby realizing the locking and unlocking operations of the upper part of the locking plate.

[0014] By adopting the above technical solution, when it is necessary to unlock the lower part of the locking plate, the second electrical component needs to be adjusted to the opening state. At this time, the control panel is operated to start the first driving member to drive the second rotating member to move, thereby driving the limit arm to rotate, and then the limit arm drives the second rotating shaft to move through the first transmission member, thereby controlling the opening of the second electrical component; at the same time, the limit arm also releases the limit on the lower baffle of the locking plate during the rotation process, and when the upper part of the locking plate is also unlocked, the locking plate can move under the action of the reset member; thereby realizing the locking of the lower part of the locking plate and the linkage with the opening operation of the second electrical component.

[0017] Optionally, the cabinet is provided with a plurality of locking bolts and a support plate for supporting the locking seat on the inner wall of the control cavity, the locking seat is provided with a plurality of waist-shaped fixing holes for the locking bolts to pass through, and the support plate is provided with a first fixing hole for the locking bolts to pass through.

[0018] By adopting the above technical solution, due to the coordinated setting of the locking bolt and the waist-shaped fixing hole, after the support plate is fixed to the bottom side of the control chamber, when the locking hole still cannot be coaxial with the locking rod after the locking plate is moved, the installation height of the locking seat can be adjusted through the waist-shaped fixing hole to ensure that the locking rod on the locking seat can be in a coaxial position with the locking hole after the movement is completed.

[0019] Optionally, the cabinet body is provided with a plurality of hooks on the side opening edges of the first wiring chamber perpendicular to the ground, the first door is provided with a slot for inserting the hooks, and the side of the first door close to the control panel is provided with a locking slot for inserting a first locking piece.

[0020] By adopting the above technical solution, when the first box door blocks the first wiring cavity, the first box door is fitted with the opening edge of the first wiring cavity, and then the hook is inserted into the slot on the first box door, and then the first locking piece is driven by the first control component to be inserted into the locking slot on the first box door, so as to lock the first box door; the first locking piece can only be pulled out of the locking slot after the first electrical component is disconnected and grounded, so as to ensure the safety performance of the first box door when it is opened.
