Description
Technical field
The utility model relates to a kind of primary cut-out, particularly relates to a kind of novel high-voltage circuit-breaker split-combination transmission gear.
Background technology
Mostly point closing operation of primary cut-out is in the market that driving insulated tension pole to move reciprocatingly by the connecting lever on main shaft realizes, and the combined floodgate excess of stroke by regulating the connector of insulated tension pole and connecting lever to change vacuum interrupter.But in main shaft, connecting lever rotates in this kind of drive, it drives the tie point of insulated tension pole and connecting lever to be that rotating shaft rotates with main shaft, thus causes the movement locus of insulated tension pole not to be rectilinear motion.This kind of drive makes primary cut-out when deciliter action, and dynamic/static contact exists the contact in the face of point, and the beginning ability of primary cut-out will be caused to reduce; In addition, because insulated tension pole drives the moving contact of vacuum interrupter to do on-rectilinear movement, the bellows of vacuum extinction indoor can be damaged in long-term work, from finally causing vacuum interrupter to destroy, the generation of security incident may be caused.
Prior art one, as shown in Figure 1 a, 1 b, utilizes oscillating bearing as the connector of insulated tension pole and connecting lever.First oscillating bearing is fixed on insulated tension pole by screw thread; Then the connecting lever utilizing bearing pin oscillating bearing to be connected to main shaft realizes transmission.The adjustment of the excess of stroke is realized with the length that is threaded of insulated tension pole by adjusting joint bearing.But in order to bearing pin can be made to be connected with connecting lever by oscillating bearing, each oscillating bearing can only rotate the integral multiple of 180 °.
At least there is following shortcoming in above-mentioned prior art one:
The program exists and the power in the perpendicular direction of connecting lever in transmission process, the direction of this power not with the axis collinear of vacuum interrupter, thus cause insulated tension pole not do straight reciprocating motion, but be made with the reciprocating motion fluctuated.
The program closes machine bearing as connector because adopt, and make insulated tension pole there will be in motion process up and down and swing, this can damage the bellows of vacuum extinction indoor;
Program regulating overtravel is very inconvenient, all needs bearing pin to regulate after connecting lever takes off at every turn;
The precision comparison of program regulating overtravel is low, and each excess of stroke can only regulate the integral multiple of 0.5mm.
Prior art two, as shown in Figure 2, the difference of the program and existing scheme 1 is, has added a transition piece adjusting rod between insulated tension pole and oscillating bearing.These adjusting rod two ends are all linked together with insulated tension pole and oscillating bearing respectively by screw thread, thus realize deciliter transmission of primary cut-out, and the adjustment of the excess of stroke changes the excess of stroke by the length that is threaded of change adjusting rod.
There is following shortcoming equally in above-mentioned existing skill two:
The program requires will there be enough spaces to install adjusting rod between connecting lever and insulated tension pole.This has run counter to the theory at present to primary cut-out Miniaturization Design;
The program exists and the power in the perpendicular direction of connecting lever in transmission process, the direction of this power not with the axis collinear of vacuum interrupter, thus cause insulated tension pole not do straight reciprocating motion, but be made with the reciprocating motion fluctuated;
The program closes machine bearing as connector because adopt, and make insulated tension pole there will be in motion process up and down and swing, this can damage the bellows of vacuum extinction indoor.
