Background technology
The load of rectifier transformer is a nonlinear impedance, the electric current that rectifier transformer valve side winding contains first-harmonic and each harmonic superposition is passed through, in order to improve power factor, reduce the side harmonics electric current, must improve the pulse number (can adopt the mode of phase shift) of rectifying installation.Along with the development of modern industry, also more and more higher to the requirement of electric power system, as guaranteeing in the constant situation of phase shift electric angle, adjust load voltage, in the constant situation of input voltage, adjust load voltage etc. according to input voltage fluctuation.Phase-shifting rectifier transformer will satisfy above-mentioned instructions for use, just must increase a voltage regulating transformer, combine with two device bodies of phase-shifting rectifier transformer, be so-called pair of machine body structure, this pair of device body transformer device structure is complicated, manufacturability is poor, material cost is high, energy loss is large, use cost is high, does not meet the requirement of energy-conservation, low-carbon (LC), environmental protection.
The utility model content
The purpose of this utility model provides a kind of single device body phase-shift voltage regulating rectifier transformer, namely can satisfy instructions for use, can realize to greatest extent again the saving of material cost and land area, reduce energy loss, realize low-carbon (LC), environmental protection, solve the problems referred to above that background technology exists.
The technical solution of the utility model is: single device body phase-shift voltage regulating rectifier transformer comprises low-voltage coil and the balance reactor winding of on high-tension side basic coil and phase shift coil, low-pressure side; On basic coil and the phase shift coil several shunting taps being set, is the meander configuration syndeton between the shunting tap of basic coil and the shunting tap of phase shift coil, shunting tap cross-over connection pressure regulation loaded switch or without the field switch connection that goes between.
Described pressure regulation loaded switch or without field switch, same half fixed contact of going up mutually connects the shunting tap of the basic coil of phase homophase, and second half fixed contact connects the shunting tap of the phase shift coil of other phase, that is to say: the pressure regulation loaded switch or without the fixed contact of field switch in the alternate connection of difference, consist of the meander configuration syndeton.
Adopt the utility model, switch by the pressure regulation loaded switch or without the contact sound of field switch, change the effective turn of basic coil and phase shift coil, that is changed the synthetic number of turn of input side, thereby reach the purpose of adjusting voltage on valve side.Because the effective turn of basic coil and each tap position of phase shift coil is corresponding proportional, thereby can guarantee that the phase shift electric angle under each tap position is invariable.
