Abstract
The utility model provides a high-voltage power supply switch and soft start combination control cabinet. A high-voltage disconnecting switch in the control cabinet is connected with a high-voltage lightning arrester, a high-voltage current transformer and a high-voltage vacuum contactor in series and then is provided with an output line of a motor stator end. An electrolyte water tank line for soft start below the control cabinet is connected with an alternating-current contactor in series and then is provided with an output line of a motor rotor end. A high-voltage switch and soft start are scientifically and reasonably combined into a whole body, so that an electromotor uniformly raises speed and stably starts under the conditions of the biggest starting torque and the minimum starting current of a peak, and the soft start function of the high-voltage electromotor is realized. The control cabinet solves many problems caused by the fact that the current high-voltage switch and soft start are separate and are respectively operated, and the control cabinet is beneficial to saving energy, protecting the environment and reducing the cost.

The 3-10KV high-voltage AC motor is widely used in every profession and trade, but since when starting electric current up to 5～7.5 times of rated current, cause impact to load; Also can cause line voltage to descend; Produce a large amount of harmful harmonic waves, increase the reactive loss of electric energy, for addressing this problem; The flexibly starting high voltage motor technology is arisen at the historic moment; Wherein Liquid Variable-resistance soft start technology with liquid resistance with the starting time can be adjusted by operating mode at random, under the underloading situation starting current smaller or equal to 1.3 times motor rated current, can start continuously three times more extensive with first-class advantage application, in the prior art, owing to multiple reason; High-tension switch cabinet and soft start all are provided with respectively, and this has all brought a lot of troubles for installation, use, maintenance and expenses.
Summary of the invention
The purpose of the utility model is to solve the technical deficiency of above-mentioned existence; A kind of high-voltage electric switch and soft start Combination Control cabinet are provided; With high-voltage electric switch and scientific and reasonable the making up of soft start, can disposable realization be controlled by detection, metering and the break-make of high voltage source.
The utility model comprises: the high voltage isolator upper end that is used for the control of high-tension electricity break-make is connected with the high pressure incoming line; The electrolyte water tank that is used for soft start is connected with rotor end outlet line, and the technical scheme that is adopted is: be provided with motor stator end outlet line after the high voltage isolator polyphone of installing above in control cubicle connects current transformer and high-pressure vacuum contactor; After connecing A.C. contactor, the electrolyte water tank circuit polyphone that the below is used for soft start in the above-mentioned control cubicle is provided with rotor end outlet line.
Between high voltage isolator and current transformer, be connected with high-voltage arrester.
Said high-voltage arrester is serially connected with high pressure insurance and high voltage potential transformer.
In the electrolyte water tank, be provided with movable plate electrode and fixed plate.
Said movable plate electrode outer end is connected with the motor that is used to regulate the movable plate electrode resistance through driving-belt.
The utility model is owing to pass through technique scheme; With high-voltage electric switch and scientific and reasonable being combined into one of soft start; When high voltage isolator closed high power supply through current transformer and high-pressure vacuum contactor be connected with the motor stator end with the electrolyte water tank with after the rotor end is connected; Can make and satisfy mechanical characteristics of motor in the starting process all the time sealing in the requirement of resistance value; Thereby can realize motor even raising speed under the situation of maximum starting torque of peak value and minimum starting current, reach the balance starting, after, motor normal in starting reaches rated speed; Adhesive rotor-end A.C. contactor; The motivation operate as normal that begins to supply power has solved prior art mesohigh switch and soft start split setting and the problems brought of operation respectively thus, has energy-saving and environmental protection and takes up an area of, is convenient to transport and the remarkable result of reduction expense expenditure with reducing.
