HKK-DZT The working principle of the contactless automatic voltage regulator for single-phase rural power grid:

HKK-SVG static var generator is a device for dynamic reactive power compensation using bridge converter composed of fully controlled power electronic devices. The basic principle is that the self-commutation bridge circuit is directly connected to the power grid in parallel through the reactor, and the phase and amplitude of the output voltage on the AC side of the bridge circuit are properly adjusted or the current on the AC side is directly controlled, so that the circuit can absorb or emit. Meet the required reactive current, so as to achieve the purpose of dynamic reactive power compensation.

DZT Single-phase rural power grid contactless automatic voltage regulator：

DZT single-phase agricultural power grid non-contact automatic voltage regulator has a simple and reliable structure, non-contact automatic voltage regulation, light weight, convenient installation, long-term maintenance-free, suitable for mountainous areas and rural remote areas, single-phase load distribution at the power grid terminal It can be installed in many places at the end of the power grid to completely solve the low voltage problem at the end of the rural power grid.

DZT single-phase agricultural power grid non-contact automatic voltage regulator is a single-phase product, and its main circuit is in the form of an autotransformer. It adopts relay or AC contactor to switch taps to achieve non-contact automatic voltage regulation, and the output voltage can be maintained at the rated value. within ±8% of value.

DZT single-phase agricultural power grid non-contact automatic voltage regulator is composed of control circuit, self-coupling voltage regulating circuit, output circuit and straight-through circuit. The control circuit samples the input voltage and compares it with the reference voltage to control the working state of the auto-coupling voltage regulator circuit. When the input voltage is low, the auto-coupling voltage regulator circuit enters the boosting working state; when the input voltage is close to the rated voltage value, the auto-coupling voltage regulating circuit exits the boosting working state and enters the straight-through working state. Green, yellow and red indicators are used to indicate the running status of the equipment.

DZT single-phase agricultural power grid non-contact automatic voltage regulator, the input end is equipped with a full-mode protection single-phase 40KA lightning surge protector (JOSLYN technology from the United States), which can effectively prevent the surge voltage intruding along the power line. voltage and subsequent loads can cause damage.
