Model PJG1 Mine-used Flameproof and I.S. Vacuum Switch for High Voltage is mainly used for dangerous places and coal mine underground with coal dust and explosive gas, providing control and protection of the power distribution system with rated voltage 10kv or 6kv, frequency 50Hz, maximum rated current 630A and ungrounded center, and also for direct starting of motor.
Model PJG1 Switch utilizes new-type circuit breakter, with the arc extinguish chamber using the technology of epoxy resin pole by APG process, really free of maintenance; the circuit breaker is installed on the cart which has uinque and flexible worm wheel to avoid the deviation of moving and static contacts caused by the former swaying unit. The switch has closedown switch for closing the brake until the cart into the setting position and I.S. communication interfaces for connecting with our power monitoring and control system. The switch also has Chinese operation interface and menus, and with advanced microprocess technology in relay protection, the switch can provide reliable control and protection for the power systems with ungrounded center or with grounding by arc extinguish coil.
