The HYJ4 type operating mechanism can be used for Shandong Hitachi High-voltage Swithgear Company 252kV Project as well as isolating switch, grounding switch and load switch which have the same required torque.
This mechanism uses clutch, worm and gear to ensure opening and closing position and output angle by forward and reverse function of motor and can finely adjust the output angle through the limit screw of the clutch device with manual and electric functions.
1.The output angle of this mechanism is 36°(can be customized according to customer requirements)
2.Output torque 250N.m
3.Rated voltage switch time ≤2S
4.CSK magnetic blow-out switch. The current that the contact can continue to pass is 10A for AC220V and 3A for DC220V.
5.F10 auxiliary switch. In general, there are two 10 opening and 10 closing auxiliary switches.
6.The secondary connector is an imported industrial connector with a protection class of IP68. One mechanism is conventionally equipped with two 46-core industrial connectors. Secondary industrial connector is available in 24, 32 and 46 needles.
7.Technical parameters of stored energy electrical machine
