The invention provides a transfer type grounding isolation switch, the isolation switch includes a base (100), two insulators (120), a second connection mechanism, a third connection mechanism and an isolation switch (150), two insulators ( 120) are correspondingly installed at both ends of the base (100), the second wiring mechanism includes a second terminal post (141) arranged on the top of one of the insulators (120), and the third wiring mechanism includes a U-shaped second hook seat ( 174) and the third terminal (171) that is arranged on the top of another insulator (120), the second hook seat (174) includes the first connection plate, the second connection plate and the third connection plate connected in sequence, the second connection The board is installed on the third terminal (171), and the isolation knife switch (150) is detachably connected with the second terminal (141), the first connecting plate and the third connecting plate respectively. The isolating knife switch is beneficial to making the isolating knife switch more reliably contact with the static contact, and is beneficial to improving the safety performance of the isolating knife switch.
Description
technical field [0001] The invention relates to the technical field of isolation switch, in particular to a transfer type grounding isolation switch. Background technique [0002] Isolation knife switch (disconnector), that is, in the open position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; in the closed position, it can carry the current under normal circuit conditions and abnormal conditions within the specified time (e.g. short-circuit) current switching device. [0003] In the current power distribution overhead lines, multiple section switches are installed on the power supply line according to the needs, and in order to shorten the power outage range and improve the reliability of power supply in the distribution network automation system, more and more section switches are needed to isolate As long as the section switch is installed on the power supply line, the isolation knife switch...
