Line parameter test anti -induction electric installation

The utility model relates to a line parameter test anti -induction electric installation, its structure does, installation switch and switch in the safety cover, switch and switch are established ties, and earthing terminal, switch one end interconnecting link end are connected to switch one end. When checking the circuit phase place, can be in a looks switch and switch and close the position, the position is divided to double -phase being in in addition. When the experimental wiring of change, can close three -phase switch and switch, with circuit ground connection, prevent that the influence electricity from hurting sb. 's feelings. With three -phase switch and switch disconnection when the test. 本实用新型涉及种线路参数测试防感应电装置，其结构为，保护罩内安装刀闸和开关，刀闸和开关串联，刀闸端连接接地端，开关端连接线路端。核对线路相位时，可将相开关和刀闸处于合位，另两相处于分位。在更改试验接线时，可将三相开关和刀闸合上，将线路接地，防止防止感应电伤人。在测试时将三相刀闸和开关断开。
