A double slip-ring slipping toothed electromagnetic clutch is provided between the second stage and the third stage, which causes the switch to accurately position, delays to cut and control the power supply circuit, and avoids the self damage of the electric operation device. The utility model has the advantages of reasonable structure, long service life and safety, is widely used for the electric power system and the electrified railway traction power supply system, and operates the outdoor high voltage insulating switch below 220KV and more than 10KV and the indoor high-voltage isolating switch below the 35KV (including the 27.5KV single-phase and two-phase).
Description
The utility model relates to the high-voltage electrical apparatus technical field.
The electronic powder operation device of isolating switch of domestic production at present, the control power supply can not be realized AC/DC.The electronic powder operation device of domestic existing isolating switch, the employing spring energy-storage mode that has because of impulsive force is big, causes isolating switch impaired, and it is unreliable to move.The employing two-stage gear that has adds the first-stage worm gear worm speed-down, but volume is big, and weight is big, and efficient is low.Existing mode all not can solve isolating switch that motor inertia the causes inaccurate phenomenon that puts in place.The electronic powder operation device of MAD13 type isolating switch that external as Japanese high high mountain factory produces; putting in place of adopting that gear drive and friction chip electromagnetic clutch overcome that motor inertia causes is inaccurate; but its machinery driving efficiency is low, and volume is big, and does not have isolating switch mechanical breakdown protective device.
The purpose of this utility model is for overcoming above-mentioned deficiency of the prior art, proposing a kind of electronic powder operation device of being made up of motor, drive system, electric control loop and casing of high voltage isolator.
Technical solution of the present utility model is to adopt the power source of AC/DC commutator series-wound motor as device.Drive system is three grades of totally enclosed type deceleration transmission, the first order is a cycloid pinwheel planetary gear transmission system, the second level and the third level adopt worm and gear to slow down, in order to solve the isolating switch that causes by the motor inertia inaccurate phenomenon that puts in place, between second level worm gear and third level worm screw, be added with two slip ring slipping toothed electromagnetic clutchs.Its function is after powder operation device driving isolating switch puts in place, auxiliary switch cuts off the control power supply immediately, the electromagnetic clutch dead electricity is thrown off, thereby transmission separates between the second level and the third level, double reduction idle running before motor inertia only drives, after isolating switch accurately puts in place like this, no longer be subjected to the motor inertia effects, solved inaccurate phenomenon because the switch that motor inertia causes puts in place.Electromagnetic clutch adopts the double brush formula, and is safe in utilization.In addition when isolating switch when there was a mechanical failure, be added in moment on the electromagnetic clutch with overrate, at this moment electromagnetic clutch skids, and makes the branch, the resultant moment that are added on the switch constant substantially, in order to avoid switch is impaired.Electric control loop in the technical solutions of the utility model, be provided with time-delay and cut off the control power circuit, this circuit is made up of integrated package, resistance R, capacitor C, relay and transistor etc., it can be 5 seconds to 120 seconds the adjustment time, when isolating switch generation mechanical breakdown, isolating switch is finished and is closed, requiredly when the separating brake required time will be greater than regular event close, opening time, and the action of control power circuit is cut off in time-delay like this, the rupturing operation power supply, thus the damage of electronic powder operation device avoided.The utility model all has door in positive and side, is convenient to maintenance and inspection.All sealing parts of electronic powder operation device casing adopt the rubber strip sealing, but dust protection is invaded.The running part of machine driven system is totally-enclosed with metal-back, prevents that various items such as dust from dropping on the contact-making surface, causes the damage of deceleration part.The utility model is provided with manual control and two kinds of actuating modes of electronic control.Manual control operation is inserted hand output shaft by handle and is finished; Electronic control operation is finished by motor, contactor and branch, switch knob.Between manual and electronic actuating, have chain, when handle inserts hand output shaft, limit switch cuts off electric operating control power supply, on the contrary, after handle was extracted from hand output shaft, the limit switch involution realized electronic control, thereby can not carry out electronic control simultaneously when satisfying manually control, guarantee safety.The utility model is provided with electric heater in case, but winter protection, dries.
The utility model has the following advantages compared to existing technology: the volume of (1) drive system is little, in light weight, and the machine driving speed ratio is big, the efficient height; (2) the integral layout compact and reasonable of this device; (3) mechanical endurance long, can reach more than 10000 times; (4) can realize manually controlling with electronic two kinds of operations, safe and reliable.
