Background

The grounding box is used for placing grounding wires and plays a role in protecting the grounding wires. The grounding box and the grounding busbar have the function of collecting the grounding wires. The three-phase grounding device is specifically divided into a direct grounding box, a protection grounding box, a three-phase cross interconnection grounding box and a three-phase six-wire grounding box. In a conventional intelligent grounding box, only parameters such as grounding circulation current, voltage and the like are monitored. But the number of discharges was not monitored.

SUMMERY OF THE UTILITY MODEL

The utility model relates to an overcome and to have foretell not enough among the prior art, provide an intelligent protection grounding box of area discharge counter that can monitor the number of times that discharges.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an intelligent protection grounding box of counter discharges in area, includes box and chamber door, the inside of box is equipped with a plurality of current transformer, a plurality of sheath protector, a plurality of PT module, a plurality of counter and a monitor of discharging, current transformer, sheath protector, PT module, the counter one-to-one that discharges, sheath protector and the counter that discharges be connected, current transformer and PT module all be connected with the monitor, the chamber door install on the box and rotate with the box and be connected.

When the high-voltage cable is used, the sheath protector is grounded after passing through the discharge counter, the sheath protector is connected with the cable sheath of the high-voltage cable, and the discharge counter can visually display the discharge times of the sheath protector; the grounding wire is respectively connected with the current transformer and the PT module, and the monitor is connected with the current transformer and the PT module and used for detecting grounding circulation and voltage parameters; and the design of the box door can be used for carrying out later-stage installation and maintenance on the components in the box body.

Preferably, the current transformer is arranged below the inside of the box body, the PT module is arranged in the middle of the inside of the box body, and the sheath protector is arranged between the current transformer and the PT module. Through the position design of current transformer and PT module, can effectual reduction influence between the two, ensure the reliable use of two parts.

Preferably, the discharge counter and the monitor are mounted above the interior of the box body, and the monitor is arranged above the discharge counter. The discharge counter and the monitor are designed in positions, so that the discharge counter and the monitor can be far away from the current transformer and the PT module, and reliable operation of the two components is ensured.

Preferably, the box door is provided with an observation window, and the observation window is arranged above the box door and corresponds to the discharge counter and the monitor. Due to the design of the observation window, data on the discharge counter and the monitor can be read visually without opening the box door, and the reliability of the grounding box is improved.

Preferably, a solar panel is arranged on the top surface of the box body and connected with the monitor. The monitor is powered through the design of the solar panel, and the reliable operation of the monitor is ensured.

The utility model has the advantages that: the discharge counter can visually display the discharge times of the protective layer protector; the monitor is connected with the current transformer and the PT module and is used for detecting grounding circulation and voltage parameters; the box door can be used for carrying out later installation and maintenance on components in the box body; the safety and the reliability are high.
