Description
Technical Field
The utility model belongs to the technical field of power distribution cabinets, and relates to a grounding structure of a power distribution cabinet body.
Background
The grounding of the electric equipment body is an important safety measure, and the power distribution cabinet is also characterized in that because of the possibility of poor contact of a hinge between a cabinet door and a cabinet body of the power distribution cabinet, in the prior art, in order to effectively ground the cabinet door, a wire (shown in fig. 2) is welded between the cabinet body and the cabinet door, then the cabinet body is connected with the ground through a grounding electrode, the wire is positioned on the inner side of the cabinet door, in order to adapt to the space required by a cabinet door switch, the wire needs to have a certain length and keep a loose state, but because the energized wire is easy to damage in the cabinet door switch process, the process of overhauling electric parts in the cabinet body, the condition that the cabinet door is extruded when being closed, and the like, the grounding connection mode of the grounding of the cabinet door is unreliable, and the attractiveness of the cabinet body and the cleanliness of the cabinet body are also influenced.
Disclosure of Invention
The utility model aims to solve the problems existing in the prior art and provides a grounding structure of a power distribution cabinet body, and the technical problem to be solved by the utility model is how to improve the grounding reliability of the power distribution cabinet door.
The aim of the utility model can be achieved by the following technical scheme: the utility model provides a grounding structure of switch board cabinet body, switch board includes the cabinet body and cabinet door, articulates through the hinge between the side of cabinet door and the cabinet body, its characterized in that, grounding structure is including setting up the limiting plate on the cabinet body curb plate that is close to hinge department, be provided with a plurality of electric subassemblies that connect between limiting plate and the cabinet door, electric subassemblies including fixing a plurality of reeds on cabinet door medial surface and the slot of setting on the limiting plate connect, the reeds can insert the electric connection of the cabinet door and the cabinet body in the slot under cabinet door closing state.
Furthermore, the slot is wedge-shaped, two reeds are symmetrically distributed, and the interval between the two reeds far away from the cabinet door is larger than the interval between the other ends.
Further, a metal wire is connected between the bottom of the slot and the cabinet door, and passes through the space between the two reeds.
Further, the cabinet body is connected with a grounding electrode through a lead.
Under the closed state of the cabinet door, the bearing of the cabinet door is limited by the structures such as the cabinet body and the cabinet door lock, so that the situation that the electric contact is unreliable exists at the hinge of the cabinet door, but under the open state of the cabinet door, the bearing of the cabinet door is borne by the hinge, so that the electric connection between the cabinet door and the cabinet body is relatively reliable. Therefore, in this scheme, cabinet door is under open condition, and hinge and wire are responsible for the electric connection between cabinet door and the cabinet body, and under cabinet door closed condition, wire advances and connects electric subassembly both to be responsible for the electric connection between cabinet door and the cabinet body, can see that in this scheme, can both realize dual electric connection under cabinet door open condition or open condition between cabinet body and the cabinet door, under the circumstances of cabinet body ground connection, make the ground connection of cabinet door comparatively reliable.
The scheme uses the power connection assembly to replace the traditional lead to connect electricity, can overcome the unordered and damaged condition of lead, and improves the neatness and the grounding reliability of the power distribution cabinet.

Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
The grounding structure of the cabinet body of the power distribution cabinet shown in fig. 1 and 3 comprises a limiting 3 plate arranged on a side plate of the cabinet body 1 close to a hinge, a plurality of power connection assemblies are arranged between the limiting 3 plate and the cabinet door 2, each power connection assembly comprises a plurality of reeds 4 fixed on the inner side surface of the cabinet door 2 and a slot 5 arranged on the limiting 3 plate, and the reeds 4 can be inserted into the slot 5 under the closing state of the cabinet door 2 to realize the electric connection between the cabinet door 2 and the cabinet body 1.
The slot 5 is wedge-shaped, two reeds 4 are symmetrically distributed, and the interval between the two reeds 4 far away from the cabinet door 2 is larger than the interval between the other ends.
A metal wire 6 is connected between the bottom of the slot 5 and the cabinet door 2, the metal wire 6 passes through the space between the two reeds 4 and is limited and enclosed by the slot and the two reeds, and the metal wire at the position is not easy to be damaged when being subjected to the switch cabinet door and can not interfere the installation of other electric parts.
The cabinet body 1 is connected with a grounding electrode 7 through a wire, and is pre-buried to be grounded when the power distribution cabinet is installed and falls to the ground.
Under the closed state of the cabinet door 2, the bearing of the cabinet door 2 is limited by the structures such as the cabinet body 1 and the cabinet door 2 lock, so that the situation that the electric contact is unreliable exists at the hinge of the cabinet door 2, but under the open state of the cabinet door 2, the bearing of the cabinet door 2 is borne by the hinge, so that the electric connection between the cabinet door 2 and the cabinet body 1 is relatively reliable. Therefore, in this scheme, cabinet door 2 is under the open condition, hinge and wire 6 are responsible for the electric connection between cabinet door 2 and the cabinet body 1, under cabinet door 2 closed condition, wire 6 advances and connects the electric connection between the electric subassembly both responsible for cabinet door 2 and the cabinet body 1, can see, in this scheme, can all realize dual electric connection under cabinet door 2 open condition or open condition between cabinet body 1 and the cabinet door 2, under the condition of cabinet body 1 ground connection, make cabinet door 2's ground connection comparatively reliable.
The scheme uses the power connection assembly to replace the traditional lead to connect electricity, can overcome the unordered and damaged condition of lead, and improves the neatness and the grounding reliability of the power distribution cabinet.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
