The utility model has simple structure which is reliable, the rectifying output average voltage and the conduction angle of the rectifying element are greatly improved, the dust collection effect is notable, which is very favorable to the environment protection, at the , the maintenance also is very convenient.
Description
The utility model relates to the appliances power source technology, specifically a kind of electrostatic precipitator high-voltage DC power supply.
Up to the present, the application of silicon-controlled voltage regulation technology in the electrostatic precipitator power supply has the history of decades, domestic aspect the static dust-removing power Study on Technology, attentiveness all concentrates in the research of control circuit, but in actual application, many problems occur on the main circuit, although automatic control technology has reached high level, dust collection effect can not be satisfactory.The silicon-controlled voltage regulation technology, the rectified waveform amplitude is a constant fixed value, therefore this value is generally greater than the electric field breakdown magnitude of voltage, in the process of boosting, when voltage is raised to when equaling breakdown voltage value, electric cleaner will inevitably be wanted flashing flashover breakdown or arc short circuit phenomenon, thereby the voltage-regulation scope is restricted, and therefore, conduction angle is little, average electrical is forced down, and is the defective that existing electrostatic precipitator power supply exists.
The purpose of this utility model is for electrostatic precipitator provides a kind of voltage magnitude adjustable, the high high-voltage DC power supply of output average voltage.
The purpose of this utility model is achieved in that
The electrostatic precipitator high-voltage DC power supply adopts three-phase alternating-current supply to connect T shape wiring transformer after high-voltage rectifier is connected to load or adopt three-phase alternating-current supply to connect three single-phase transformers after high-voltage rectifier is connected to load through three-phase induction regulator through three-phase induction regulator.
The utility model is simple in structure, and is reliable, improved rectifier cell conduction angle and rectification output average voltage greatly, makes dust collection effect remarkable, highly beneficial to environmental protection, safeguards also very convenient simultaneously.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model circuit structure diagram
Fig. 2 is another embodiment of the present utility model
Consult Fig. 1, the utility model is made up of three-phase induction regulator 1, T shape wiring transformer 2, high-voltage rectifier 3, electric field capacity load 4, three-phase alternating-current supply is powered to three-phase induction regulator 1 through air switch ZK, the output of three-phase induction regulator 1 connects T shape wiring transformer 2, is connected to load 4 by T shape wiring transformer 2 behind high-voltage rectifier 3 again.
The utility model connects by T shape wiring transformer with two single-phase transformers, three phase mains can be become two single phase alternating current power supplies, and establishing wherein, a transformer number of turn is W1 and mid-point tap is arranged that another number of turn is
12W1, their the secondary coil number of turn all is W2, then primary winding is received on the three-phase induction regulator 1, two secondary coils just can produce the biphase equilibrium voltage of 90 ° of equal and opposite in directions, phase phasic difference, two single phase poaer supplies of T shape wiring transformer secondary coil are formed bridge-type with high-voltage rectifier be connected series connection output, voltage is two 2 pulse wave electric voltage sums, owing to have 90 ° of phase differences between two single phase poaer supplies, can obtain the output of 4 pulse wave direct current energies.
Consult Fig. 2, it is the utility model another embodiment, three-phase alternating-current supply supplies power to three-phase induction regulator 1 through air switch ZK, and the output of three-phase induction regulator 1 connects 2, three single-phase transformers 2 of three single-phase transformers and be connected to load 4 behind high-voltage rectifier 3.Adopt three-phase induction regulator 1 as AC voltage adjusting, just can obtain the adjustable three-phase alternating-current supply of amplitude voltage and give three single-phase transformer power supplies, in order to improve rectification output average voltage, adopt three-phase high-voltage bridge-type connecting circuit, output voltage is three 2 pulse wave electric voltage sums, owing to there are 120 ° of phase differences between three voltages, can obtain the output of 6 pulse wave direct current energies.
Two technical schemes of the present utility model use operating process identical, during start, close air switch ZK earlier and send to circuit; then, press three-phase induction regulator 1 Electric Machine Control schematic diagram operation pressure regulation, when DC voltage rising behind set-point; stop to boost, elder generation's step-down is shut down again during shutdown.
