一种电缆局放高通滤波接头

Partial discharging high-pass filtering joint of cable

Abstract

The utility model discloses a partial discharging high-pass filtering joint of a cable. The joint comprises a T-shaped joint (1), a filter housing (2), an insulating pad column (3), and a filter body (4). The filter body (4) is connected with the filter housing (2) through threads. The filter housing (2) is connected with the T-shaped joint (1) through threads. A male joint (5) is connected with a partial discharging acquisition system (8). A female joint (6) is connected with a cable internal partial discharging sensor (7). Technical effects of the joint are that through connecting the filtering joint, pre-filtering of input signals of the partial discharging acquisition system and ground protection of high-voltage signals are realized, thereby providing convenience for development of subsequent test operation, and filtering effects can be adjusted according to signal characteristics. Thus, cost is saved, and reliability of subsequent signal acquisition is improved.
本实用新型公开了一种电缆局放高通滤波接头,包括T型接头(1)、滤波器外壳(2)、绝缘垫柱(3)、滤波器本体(4),滤波器本体(4)通过螺纹与滤波器外壳(2)连接,滤波器外壳(2)通过螺纹与T型接头(1)连接,公头(5)连接局放采集系统(8),母头(6)连接电缆内置局放传感器(7)。本实用新型的技术效果在于通过连接滤波接头实现局放采集系统输入信号的预滤波和高压信号的接地保护,方便了后续测试工作的展开,并可根据信号特点调整滤波效果,节约成本,提高了后续采集信号的可靠性。
