Abstract
The utility model provides a positive and negative polarity conversion direct current voltage generator's transmission, is provided with direct current voltage generator, is equipped with transmission structure in the direct current voltage generator, and drive mechanism comprises insulating lead screw and motor, and the motor drives insulating lead screw and does exercises, is equipped with the silicon stack in the direct current voltage generator, is equipped with fixation nut on the silicon stack, and the motor drives fixation nut and does exercises. Be equipped with insulating lead screw in the direct current voltage generator, through the cooperation campaign of insulating lead screw with the motor, the positive negative polarity with the silicon stack that can be quick is changed, and positive and negative polarity conversion is convenient, owing to adopt insulating lead screw and motor, has avoided traditional adoption gear drive's mode, need not set up the oil circuit, has avoided the phenomenon that appears seepage oil in the silicon stack for the transmission operation is more stable, and the contact is good.
Description
Technical field
The utility model relates to a kind of transmission device, has the transmission device relating to a kind of positive-negative polarity conversion dc voltage generator.
Background technology
DC voltage generator is mainly used in the change of current and becomes, DC bushing, direct current cables, DC circuit breaker, the DC break down voltage of the High-Voltage Electrical Appliances such as smoothing reactor, the investigation test such as polarity inversion and partial discharge, form test and routine test of dispatching from the factory, DC generator positive-negative polarity conversion in the past has several mode: manually regulate, silicon stack is pulled down, load onto after changing cathode and anode directions and (install inconvenient, not only consuming time but also effort, also will by ascending a height, lifting appliance etc.), by gear driven power transmission shaft in internal conversion, power transmission shaft and flange are equipped with movable sealing, oil circuit oil pipe.(high, the unstable properties of this kind of sealing structure difficulty, easily leakage of oil, complex structure, cost, maintenance inconvenient), changes original internal gear transformational structure into exterior insulation screw rod transmission to solve the problems of the technologies described above.As long as this silicon stack solves the insulation dielectric strength of screw mandrel and the tear resistance of screw mandrel, there is no movable sealing, there is no oil circuit oil pipe, so there is not leakage of oil and unstable properties phenomenon.
Summary of the invention
It is convenient that the purpose of this utility model is to provide a kind of conversion, the transmission device of a kind of positive-negative polarity conversion dc voltage generator of good stability.
The technical solution of the utility model is: a kind of transmission device of positive-negative polarity conversion dc voltage generator, be provided with DC voltage generator, drive mechanism is provided with in described DC voltage generator, transmission mechanism is made up of insulate screw mandrel and motor, driven by motor insulation screw mandrel moves, be provided with silicon stack in DC voltage generator, silicon stack is provided with hold-down nut, and driven by motor hold-down nut moves.
Described insulation screw mandrel is positioned at the inner side of DC voltage generator, and motor is interconnected with insulation screw mandrel, and motor is positioned at the bottom of DC voltage generator.
Described DC voltage generator side is provided with roller, and described silicon stack is that M shape is distributed in DC voltage generator, and silicon stack one end is fixed with hold-down nut.
Described silicon stack side is interconnected with insulation screw mandrel, and the hold-down nut of driven by motor insulation screw mandrel and silicon stack one end moves up and down, and the motion of insulation screw mandrel changes the both positive and negative polarity of silicon stack.
The utility model has the advantages that: in DC voltage generator, be provided with insulation screw mandrel, by the routing motion of insulate screw mandrel and motor, fast the positive-negative polarity of silicon stack can be changed, positive-negative polarity conversion is convenient, owing to adopting insulation screw mandrel and motor, avoids the gear-driven mode of traditional employing, do not need to arrange oil circuit, avoid in silicon stack the phenomenon occurring leakage of oil, transmission device is run more stable, contact is good.
