Described adjustment grease chamber is cylinder, arranges piston in described cylinder, arranges limit switch in described cylinder, and described limit switch is connected with PLC.
The utility model is by the observation to existing circuit breaker, find the power resources regulating the piston in grease chamber as circuit breaker, it is mainly at valve A, valve B, valve C, valve D and oil pump are under the control of PLC, effective opening and closing valve, and by finding the observation of valve, valve A and valve B has hydraulic oil to pass through all the time, therefore purification mechanism is set on its two-way oil pipe, and control numerous valve and oil pump by PLC, make it can the motion of control piston, and piston is at the volley due to can not smooth running in order to what prevent its excess of stroke from causing hydraulic pressure installation, therefore between the valve C regulated in grease chamber and valve D, opening arranges position limit switch, be convenient to carry out control operation.
Valve A, valve B, valve C, valve D are electronic control valve, for the ease of distinguishing because this has been different names.
Grease chamber is regulated to be divided into Liang Ge grease chamber in principle, i.e. high-pressure oil chamber and low pressure grease chamber, the position of this Liang Ge grease chamber is relatively-stationary, but the working state residing for circuit breaker is different, high-pressure oil chamber can become low pressure grease chamber by abrupt release hydraulic oil, and low pressure grease chamber becomes high-pressure oil chamber simultaneously, suppose piston left end connecting breaker contact, then circuit breaker is in the moment of combined floodgate, the piston in grease chamber is regulated to be in the right side regulating grease chamber, now open valve B, valve C also opens oil pump, high pressure liquid force feed on the left of piston can be extracted out by it, piston is to left movement simultaneously, right side is made to become zone of high pressure, and now because hydraulic oil is through the purification mechanism at valve B place, arriving of hydraulic oil is filtered, when needs disconnect, then throttle down B and valve C, open valve A, valve D and oil pump, the low pressure grease chamber in left side is made then to become high-pressure oil chamber, hydraulic oil enters in oil sump by valve A, it is through purification mechanism, by filter core, hydraulic oil is filtered, it can be purified hydraulic oil, make in its process can run at Hydraulic Mechanism of Circuit-breaker, hydraulic oil is filtered, it can continually be filtered, thus ensure the pure of hydraulic oil.
The utility model purifies hydraulic oil in day-to-day operation, in order to ensure that the carrying out of enough continuous and effective purifies, avoiding the drawback needing long-time power-off to close a floodgate when overhauling, also in order to avoid the phenomenon more renewing hydraulic oil of saving time, not only reducing the input of cost, also ensure that the stable operation of Hydraulic Mechanism of Circuit-breaker, and due to the control of PLC, make valve be in the state automatically controlled, position limit switch is set simultaneously, ensure that the safety and stablization of operation, be worthy to be popularized and application.
