Description
Technical field
The present invention relates to a kind of isolating switch control apparatus for electrically-operated mechanism, be installed in the motor-operating mechanism of high voltage isolator, the rotating realizing direct current machine by two groups of contactors and two groups of limit switches switches, automatic cut-off power after operating mechanism puts in place.
Background technology
The motor-operating mechanism of current isolating switch, as the actuator of disconnecting switch operation deciliter, its security reliability receives much concern, under normal circumstances, the rotating that motor-operating mechanism adopts contactor, relay mode controls motor switches, and motor-operating mechanism is long-term electriferous state, the instruction of Long-distance Control divide-shut brake is the dry contact triggering motor drive mechanism self-holding circuit, motor utilizes self-holding circuit to complete residue action, and automatic cut-off power, enter holding state.Because remote transmission signal exists decay and interference problem, easily cause the conducting of motor-operating mechanism self-holding circuit, and then cause the fault such as malfunction, tripping of motor-operating mechanism, make electric railway power supply-distribution system there are major safety risks.
Summary of the invention
In order to solve Problems existing in above-mentioned technical pattern, the object of this invention is to provide a kind of isolating switch control apparatus for electrically-operated mechanism, can effectively solve the faults such as motor-operating mechanism malfunction, tripping, effectively reduce the failure rate of railway power supply-distribution system, for high-tension line action stability provides a favorable security.
In order to solve the problem, the technical solution used in the present invention is to provide a kind of isolating switch control apparatus for electrically-operated mechanism, wherein: this device comprises separating brake limit switch, limit switch mounting panel, limit switch construction bolt, fastening bolt, limiting plate, screw, combined floodgate limit switch, separating brake contactor, closing contactor, guide rail, motor, adjusting bolt, main transmission.
Described separating brake limit switch and combined floodgate limit switch are fixed respectively by limit switch construction bolt and limit switch mounting panel, limit switch mounting panel is arranged on the two ends of main transmission respectively by adjusting bolt, limiting plate and screw are fixed by fastening bolt, and separating brake contactor and closing contactor are fixed by guide rail and main transmission.
Effect of the present invention is by original electric operating and control unit simplicity, and concentrates in operating mechanism case, and except for except the electric loop of divide-shut brake action and locality/distant place converting unit, Long-distance Control and other auxiliary units all adopt control room to arrange.Control room provides two-way power supply, directly controls motor positive and inverse, and motor-operating mechanism can complete residue action voluntarily, automatic cut-off power after operating mechanism puts in place.Because motor-operating mechanism requires that cutting off motor power DC220V, 300W direct current machine rated current is voluntarily 1.4A, and the direct current cut-out of limit switch is about 0.27A, and contactor coil attract current is about 0.039A, this Novel control device adopts limit switch to cut off contactor coil, thus cuts off motor power.The instruction of Long-distance Control divide-shut brake is two-way DC power supply, and control the rotating operation of motor respectively, when release, limit switch cuts off contactor coil power supply, and then cuts off motor power.

Embodiment
By reference to the accompanying drawings isolating switch control apparatus for electrically-operated mechanism structure of the present invention is illustrated.
Isolating switch control apparatus for electrically-operated mechanism of the present invention removes self-holding circuit apparatus design thought, the operating mechanism non-action time is not charged, when needs carry out telemechanical operation, control room provides two-way DC220V power supply respectively as the divide-shut brake instruction of motor-operating mechanism, the rotating action of direct control motor, both can be cost-saving, effectively can solve again long distance signal transmission decay and disturb the fault such as malfunction, tripping caused.
Isolating switch control apparatus for electrically-operated mechanism structure of the present invention is, this control device comprises 1, separating brake limit switch 2, limit switch mounting panel 3, limit switch construction bolt 4, fastening bolt 5, limiting plate 6, screw 7, combined floodgate limit switch 8, separating brake contactor 9, closing contactor 10, guide rail 11, motor 12, adjusting bolt 13, main transmission.
Described separating brake limit switch 1 and combined floodgate limit switch 7 are fixed respectively by limit switch construction bolt 3 and limit switch mounting panel 2, switch installation board 2 adjusting bolt 12 is arranged on main transmission 13 two ends respectively, limiting plate 5 is fixed with screw 6 fastening bolt 4, and separating brake contactor 8 and closing contactor 9 are fixed by guide rail 10 and main transmission 13.
When mechanism is in gate-dividing state, remote switching order provides 220V DC power supply, the now normally closed node conducting of combined floodgate limit switch 7, and closing contactor 9 adhesive, motor 11 starts to carry out feed motion.When screw 6 leaves open position, the normally closed node conducting of separating brake limit switch 1, for separating brake action is next time prepared.Screw 6 continues to move along combined floodgate direction, when the output shaft of main transmission 13 moves rotation to 85 ° by the right side of screw 6, combined floodgate limit switch 7 is backed down, its normally closed node disconnects, now closing contactor 9 dead electricity, motor 11 dead electricity, it is dynamic along combined floodgate direction action to 90 ° that screw 6 utilizes inertia to continue, feed motion terminates, and combined floodgate limit switch 7 can be disconnected angle and adjust 85 ° to 87 ° scopes by adjusting bolt 12.Otherwise, when mechanism is in "on" position, long-range separating brake order provides 220V DC power supply, the now normally closed node conducting of separating brake limit switch 1, separating brake contactor 8 adhesive, motor 11 starts to carry out separating brake action, when screw 6 leaves closing position, the normally closed node conducting of combined floodgate limit switch 7, for feed motion is prepared next time.Screw 6 continues to move along separating brake direction, when the output shaft of main transmission 13 moves rotation to 85 ° by the left side of screw, separating brake limit switch 1 is backed down, its normally closed node disconnects, now separating brake contactor 8 dead electricity, motor 11 dead electricity, screw 6 utilizes inertia to continue along separating brake direction action to 90 °, separating brake release, separating brake limit switch 1 can be disconnected angle and adjust 85 ° to 87 ° scopes by adjusting bolt 12.Perseveration like this, realizes the breaking-closing operating of motor-operating mechanism.
