Abstract

The invention relates to circuit induction adjustment equipment, in particular to a high-voltage adjustable reactor applied to resonance power-frequency high-voltage test devices. The high-voltage adjustable reactor comprises a reactor main body, a supporting frame and a transmission mechanism, wherein the reactor main body is composed of a movable iron core, a static iron core and a coil, the supporting frame performs fixing and supporting functions on the reactor main body, and the transmission mechanism is used for moving the movable iron core. The transmission mechanism comprises a first screw rod arranged inside the movable iron core, a first turbine sleeved on the end portion of the first screw rod, a first worm inserted into the movable iron core and meshed with the first turbine on the end portion of the first screw rod, and a drive device arranged on the end portion of the first worm. Compared with the prior art, the high-voltage adjustable reactor uses the high-precision turbine and the high-precision worm for transmission, and due to the fact that meshing faces of the turbine and the worm are in line contact, bearing capacity of the reactor is greatly higher than that of a common transmission mechanism.

Description

technical field [0001] The invention relates to a circuit sensing device, in particular to a high-voltage adjustable reactor used in a resonant power frequency high-voltage test device. Background technique [0002] Nowadays, the high-voltage adjustable reactor is used to limit the current impact caused by the sudden change of the grid voltage and the operating overvoltage, smooth the peak pulse contained in the power supply voltage, or smooth the voltage defect generated when the bridge rectifier circuit commutates, effectively protecting the frequency conversion It can not only prevent the interference from the power grid, but also reduce the pollution of the harmonic current generated by the rectifier unit to the power grid. At present, the high-voltage adjustable reactor based on the principle of adjusting the gap length of the magnetic circuit has been widely used in AC tests of large-capacity power equipment such as GIS, cables, and large generators. It can also be us...
