Description

Technical Field

[0001] This application relates to the technical field of recloser terminals, and particularly to a recloser terminal that is easy to maintain. Background Technology

[0002] Pole-mounted reclosers are intelligent switching devices for power distribution automation. In terms of breaking performance, they are equivalent to circuit breakers, but with the added function of multiple reclosing. When used in conjunction with circuit breakers, they can determine the nature of the fault and take automatic action. In addition, in terms of protection and control, they have their own fault detection function, current nature determination function, and opening and closing function. Their automatic functions and protection and control functions do not require additional operating devices. In actual use, when reclosers are used in conjunction with each other or with sectionalizers, they can automatically perform multiple breaking and reclosing control when a line fault occurs, which can significantly improve the reliability of power supply. However, after long-term use, the line connection terminals of reclosers are prone to loose connections.

[0003] In the existing technology, the recloser usually adopts a solid-sealed pole structure to form the recloser pole. This type of recloser pole is integrally pressed and molded, which is not convenient for staff to maintain its internal structure and reduces the convenience of maintenance. Utility Model Content

[0013] In some alternative embodiments, the cross-sectional area of ​​the hollow spherical head is smaller than the cross-sectional area of ​​the limiting piece.

[0048] To facilitate understanding, the working principle of this application is further described as follows: The recloser pole is easy to maintain. The electrical components inside the encapsulation housing 10 are reserved with wires. The length of the reserved wires is based on the position of the wire ends at the upper inlet connector 21 and the lower outlet connector, respectively. When the operator energizes the electrical components inside the encapsulation housing 10, he / she can first pass the wires through the upper inlet connector 21 and the lower outlet connector, and then connect them with the corresponding reserved wire ends, so that the corresponding wire connection position is always in the upper inlet connector 21 and the lower outlet connector.

[0049] During use, when a wiring position needs to be inspected, the upper inlet connector 21 can be pulled out to expose the wiring position. At this time, the staff can carry out the inspection. After the inspection is completed, the staff should keep the corresponding wire connection position at the upper inlet connector 21 and the lower outlet connector, and hold the upper inlet mechanism 20, align it with the upper connector 11 and press it down so that the spherical end of the hollow ball-shaped clamp 242 matches the clamp slot 10A, thus completing the installation of the upper inlet mechanism 20. The operation process of the lower outlet mechanism 30 is the same, which effectively improves the maintenance efficiency and convenience of the staff.
