Description
Technical field
The present invention relates to a kind of mechanical automatic transmission, particularly a kind of damping resistance automatic switching control equipment.
Background technology
At the scene in high-potting and the on-line insulation monitoring device, the voltage source of voltage-phase and amplitude accurately need be provided sometimes, detect for use in insulation parameter accurately.Adopting standard capacitance dividing potential drop mode to obtain accurate voltage is a kind of very effective mode; In general bleeder mechanism all will could insert bus under power down mode, in order to realize inserting and withdraw from bus under the electriferous state safely and effectively, and has developed a kind of charged angle ratio measurement mechanism; This device need insert operating system with high voltage standard capacitor; But simply high voltage standard capacitor is inserted high-pressure system can cause serious transient state process, and the transient overvoltage amplitude that is occurred is higher, and the danger of breakdown potential container major insulation is arranged when serious; Transient overvoltage during suppression capacitor access that therefore something must be done to is to guarantee safe access.When capacitor inserts high-pressure conductor, can effectively suppress its transient state process at capacitor loops installing damping resistance, reduce the superpotential amplitude significantly, guarantee that safety inserts and withdraws from.Damping resistance is after capacitor inserts completion, and its resistance can produce the extra voltage angular difference, influences the secondary voltage precision.Therefore must be with the damping resistance bypass.So that obtain more high-precision voltage source signal.Yet, damping resistance need with high-voltage conducting wires near with touch, have safe access problem, therefore need provide a kind of automatic switchover system to operate.
Summary of the invention
The objective of the invention is to overcome the weak point of prior art, and propose a kind of charged switching damping resistance of can realizing, safe and effective damping resistance automatic switching control equipment.
The present invention realizes through following approach:
Damping resistance automatic switching control equipment, its structural feature are, include damping resistance branch road, bypass electrode branch road, transmission gear member and device framework; The device framework is installed on the jacking gear, has two groups of track-type facilitiess in its framework, and these two groups of parallel distributions of track-type facilities also are installed in the both sides of transmission gear member respectively; The damping resistance branch road includes the damping resistance member and first driving rack; The damping resistance member supports is installed in the top ends of first driving rack; And be positioned at the top of device framework; Wherein one group of track-type facilities is passed in the lower end of first driving rack, and is in transmission connection with a side of transmission gear member; The bypass electrode branch road includes bypass electrode member, second driving rack and counter weight device; The bypass electrode member supports is installed in the top ends of second driving rack; And be positioned at the top of device framework; Another group track-type facilities is passed in the lower end of second driving rack, and is in transmission connection with the opposite side of transmission gear member, in the bottom of this second driving rack counter weight device is installed.
Like this; Just formed a kind of mechanical linkage structure by first driving rack, second driving rack and transmission gear member; The device framework is a kind of conduction framework, can conduct electricity and mainly is electrically connected jacking gear and damping resistance branch road and bypass electrode branch road, and its concrete principle of work is following:
1, under normal condition; Because counter weight device is a kind of gravity block with certain mass; The bypass electrode branch road is in the falling-threshold position all the time under the effect of this counter weight device like this, under the engagement limits of mechanical linkage structure, makes left side damping resistance be in the rising extreme position all the time.
2, when carrying out access operation; Jacking gear begins to rise, and rises and drives the up lifting of damping resistance member through driving the device framework, in case top damping resistance member runs into the top high-voltage conducting wires when stopping; Just can stop to rise, accomplish the technique effect that it effectively suppresses transient state process; This moment, jacking gear then continued lifting; Cause relative top high-voltage conducting wires that the damping resistance member is produced a downward pressure; Force the downward relative motion of damping resistance member, whole damping resistance member began to install framework relatively and moved downward this moment, and the transmission gear member in the middle of below first driving rack drives in moving downward process rotates; And then drive second driving rack and begin slow rising, drive the right bypass electrode member by second driving rack and upwards rise.
3, when bypass electrode rises and touches the top high-voltage conducting wires, also can receive the barrier effect of lead, make the bypass electrode branch road also stop upward movement, this moment, bypass electrode member and damping resistance member touched high-voltage conducting wires simultaneously, and damping resistance is by bypass.This moment, jacking gear stopped upward movement, and access procedure finishes.
4, when withdrawing from operation; Its process is then with above-mentioned just in time opposite, and jacking gear begins to descend, because the effect of counter weight device; Left and right sides both arms counterweight is uneven; The bypass electrode branch road will descend and separate with lead with jacking gear, and the bypass electrode branch road descends also and to drive the transmission gear member rotation in the middle of the below through the second driving rack transmission, and then drive the lifting that makes progress of first driving rack; The damping electrode member is then constantly risen in support, and remain the contact condition of lead; When the bypass electrode branch road reached the lower limit lowest order, the damping electrode no longer rose, and jacking gear just drives device framework and the landing downwards together of damping resistance branch road, separates with high-voltage conducting wires gradually and accomplishes the whole process that withdraws from operation, and the process that withdraws from finishes.
Damping resistance automatic switching control equipment of the present invention has realized that through mechanical motion mode damping resistance is inserting and withdrawing from the switching in the process; Avoid adopting the switching device shifter of circuit structure; Guaranteed that standard capacitance inserts and the safe operation of withdrawing from process, and do not disturbed and influence.Said damping resistance branch road only plays a role in the transient state process that inserts high-voltage conducting wires, and after inserting completion, then automatically by bypass, makes measurement data unaffected.And in the high-field electrode separation process, insert damping resistance again automatically, bring into play the effect of damping resistance once more.This apparatus structure is simple; Need not power control; Handling safety is reliable, can reduce as far as possible standard capacitance is inserted and interference and the influence of withdrawing from process, has guaranteed to insert damping resistance in the moment of needs; Break off damping resistance when not required, realized that fully the safety of standard capacitor inserts and withdraws from.
The present invention can further be specially:
Every group of track-type facilities includes two cover pulley blockss of vertical distribution up and down, and every cover pulley blocks all includes symmetrical two pulleys, two middle guide holes that are provided with adaptive first driving rack and second driving rack of pulley.
The center of the guide hole of two of vertical distribution cover pulley blockss is on the same axis up and down, forms the member of two one lines, and such first driving rack and second driving rack just can be realized linear movement.
The two cover pulley blockss up and down of every group of track-type facilities are distributed in the above and below of transmission gear member respectively.
Like this, can make whole mechanical linkage compact conformation, operational reliability greatly improves.
Below the transmission gear member, has a pressure transducer, the motor power control linkage in itself and the jacking gear.
After bypass electrode member and damping resistance member touched high-voltage conducting wires simultaneously, this moment, jacking gear still had the up trend of motion, and relative high-voltage conducting wires will apply downward pressure through first driving rack in bypass electrode branch road and the damping resistance branch road and second driving rack; About two driving racks when the transmission gear member is applied equidirectional power; The transmission gear member can't rotate, and can be exerted pressure downwards by drive, make pressure transducer start; And send signal and give the control of the motor power in the jacking gear; Thereby powered-down stops motor and rotates, and jacking gear stops upward movement.
In sum; The invention provides a kind of damping resistance automatic switching control equipment; Realized that through mechanical motion mode damping resistance is inserting and withdrawing from the switching in the process, damping resistance is only played a role in the transient state process that inserts high-voltage conducting wires, and after access is accomplished; Then, make measurement data unaffected automatically by bypass.And in the high-field electrode separation process, insert damping resistance again automatically, bring into play the effect of damping resistance once more.This device is realized switching by thrust and counterweight; Need not provides power to control in addition; Simple in structure, be easy to processing and make, to need applicability preferably all being arranged by the occasion that damping resistance suppresses transient overvoltage and the high pressure of the capacitive apparatus of the control that tightens security inserts.
