Three-phase voltage regulator

Abstract

The invention discloses a three-phase voltage regulator which comprises a handle, a shell, an adjusting knob, alarm indicating lamps, a front panel, vent holes, a displayer, a switch, a voltage inputswitch, a wire, a binding post, a rear panel and a voltage output switch. The three-phase voltage regulator has the advantages that the three-phase voltage regulator is reasonable in design, the two ends of the handle and the shell of the voltage regulator are connected together through rotary shafts, the voltage regulator can be operated by one hand of an operator conveniently, the voltage regulator is taken up and is convenient to carry, a large number of heat radiating holes are formed in the positions, on the two sides of the voltage regulator, of the shell, the heat radiating holes are formed in the two sides of the shell of the voltage regulator, a dustproof screen is arranged on the heat radiating holes, and heat in the regulator can be dissipated fast, and meanwhile it is avoided that external dust enters the regulator to damage a control mainboard. The bottom end of the displayer is embedded into the front panel, the interior of the displayer and a display unit circuit are connected together, the voltage value can be observed conveniently, then the adjusting knob is operated, and the adjusting knob is adjusted to the needed voltage value.

Description

technical field [0001] The invention relates to a voltage regulator, in particular to a three-phase voltage regulator, and belongs to the technical field of voltage regulation. Background technique [0002] A voltage regulator provides a regulated output voltage using an unregulated input voltage using a feedback loop that attempts to maintain the output voltage at the voltage level of the desired output voltage, in response to connecting a load to the regulator output, The output voltage drops and the output current increases, and in conventional regulators, the recovery of the output voltage level to the desired output voltage level lags in time and negatively affects the performance of the regulator.

[0002] A voltage regulator provides a regulated output voltage using an unregulated input voltage using a feedback loop that attempts to maintain the output voltage at the voltage level of the desired output voltage, in response to connecting a load to the regulator output, The output voltage drops and the output current increases, in a conventional regulator the recovery of the output voltage level to the desired output voltage level lags in time and negatively affects the performance of the regulator

[0003] At present, most of the voltage regulators in the existing technology are five-speed voltage regulation, and the installation of product components is relatively scattered. Diodes and relays are installed in the cabinet, signal indicators and control switches are installed on the front panel, and the voltage regulation range varies. Different; there are several levels of voltage regulation, there are several transient suppression diodes and corresponding relays, first, the connection between the relay and the control switch, the connection between the signal, the indicator light and the control switch, etc., there are many connection points , complex installation, inconvenient maintenance

Second, it is bulky and not easy to carry. Third, the manual adjustment is heavy, and the carbon brush contact coil is not shock-resistant and expensive.
