Description
Technical Field
The invention relates to the technical field of cable branch boxes, in particular to an integrated cable branch box.
Background
In the power transmission and distribution system, a cable branch box is used as a key node to bear the important tasks of safe, stable and efficient connection and branching. Along with the continuous expansion and intelligent development of the power network, the integrated cable branch box gradually becomes the mainstream choice in the power facilities due to the advantages of compact structure, high functional integration level, convenient maintenance and the like. However, in the process of overhauling and maintaining the cable branch box, a potential safety hazard which cannot be ignored, namely, an electrostatic problem, gradually emerges from the water surface.
Static electricity, a common physical phenomenon in electrical power systems, accumulates and discharges potentially threatening personnel and equipment. When the cable branch box is opened for overhauling and maintaining, if a large amount of static electricity exists on a human body, not only electric faults can be possibly caused, but also the human body can be directly injured by tip discharge, so that maintenance personnel are uncomfortable and even injured. Therefore, the human body static electricity removing operation according to the safety flow is an important precondition for ensuring the smooth maintenance work and the safety of personnel.
When a part of maintenance personnel performs maintenance tasks, the step of removing static electricity of a human body may be skipped to directly perform equipment operation due to consideration of time efficiency or operation convenience. This behavior undoubtedly increases the risk of electrostatic discharge leading to damage to the device or electric shock to personnel. In addition, the possible point discharge phenomenon in the process of removing the static electricity of the human body also causes partial maintenance personnel to generate conflict psychology due to worry about electric shock, thereby further aggravating the neglected degree of the static electricity removing operation of the human body, and the root cause of the problems is that the cable branch box generally lacks corresponding forced measures or forgetting prevention measures in the aspect of removing the static electricity of the human body, so that the maintenance personnel can skip the static electricity removing operation of the human body, and meanwhile, the situation that the maintenance personnel forgets to remove the static electricity of the human body is easy to occur because no direct correlation exists between the static electricity removing operation of the human body and the maintenance operation of the cable branch box.
Accordingly, there is a need for an integrated cable breakout enclosure that overcomes the above-described problems.

When the person pulls the door body 2, the hand presses the pressing plate 32, so that the pressing plate 32 rotates, and the sliding sheet 362 is driven to slide on the resistance wire 361, so that the resistance of the resistance changing assembly 36 is gradually reduced, and the static electricity of the human body can be completely eliminated;
Meanwhile, when the hand of a person presses the pressing plate 32, the hand is influenced by the elasticity of the first spring 37, the finger of the hand deforms, the joint area of the finger and the electrode 33 is increased, human static electricity can be better led out, meanwhile, the dissipation area of the electric charge is increased by increasing the joint area of the finger and the electrode 33, and discomfort of human static electricity during elimination is further avoided.
