Accompanying drawing explanation
Fig. 1 is the structural representation of energy-saving pressure-regulation type amorphous alloy distribution transformer of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
As it is shown in figure 1, the energy-saving pressure-regulation type amorphous alloy distribution transformer of the present embodiment, including main transformer B1, series transformer B2, switch K1 and switch K2；Switch K1, K2 possess battle and close point, and make war and close point linkage, make war and become close point after switching line band electricity, and close point becomes makes war；The vice-side winding of main transformer B1 connects the primary side winding of series transformer B2, and the vice-side winding of series transformer B2 has 3 taps, and these 3 taps connect described switch K2 close point respectively, switch K2 is made war and switch K1 is made war；Switch K2 close point, switch short circuit in parallel K2 battle are at the outfan of main transformer B1 vice-side winding；Switch K1 is made war and is connected to series transformer B2 primary side winding leading-out terminal；Switch K1 close point is connected in parallel on series transformer B2 primary side winding two ends.
The output voltage of above-mentioned energy-saving pressure-regulation type amorphous alloy distribution transformer can be adjusted as required, achieve the output voltage remained stable for when distribution network voltage changes, thus greatly reducing equipment own loss and the probability of infringement electrical equipment, effectively solve the problem that existing distribution transformer output voltage is unstable.
In above-mentioned design, switch K1, K2 possess battle and close point, and make war, close point linkage, after switching line band electricity make war become close point, close point become make war.Such design switch speed is fast, and synchronicity is high, handoff procedure output voltage continuously, not power-off.
The operating condition of the energy-saving pressure-regulation type amorphous alloy distribution transformer of the embodiment shown in Fig. 1:
When switch K1, switch K2 line bag all not charged time, series transformer B2 not pressure regulation；When switch K1 line band is electric, switch K2 line bag is not charged, series transformer B2 output voltage improves 10%；When switch K1, switch K2 line bag all charged time, series transformer B2 output voltage improve 20%.
The control method of the energy-saving pressure-regulation type amorphous alloy distribution transformer of the present embodiment is:
(1) detect series transformer B2 output end voltage in real time, when output end voltage is 342V～407V, perform step (2)；When output end voltage > 407V time, perform step (3)；When output end voltage < during 342V, performs step (4)；
(2) it is failure to actuate, namely maintains the former position of the switch；
(3) lower one grade of blood pressure lowering, perform step (6)；
Lowering the operation of one grade of blood pressure lowering specifically: if original position is set to switch K1, when switch K2 line bag is all charged, be then adjusted to switch K1 line band electricity, switch K2 line bag is not charged；If original position is at switch K1 line band electricity, when switch K2 line bag is not charged, then it is adjusted to switch K1 line bag and switch K2 line bag is all not charged；
(4) raise one grade of boosting, perform step (5)；
Raise one grade boosting concrete operations be: if original position switch K1, switch K2 line bag all not charged time, then be adjusted to switch K1 line band electricity, switch K2 line bag not charged；If the former position of the switch is at switch K1 line band electricity, when switch K2 line bag is not charged, then it is adjusted to both charged；
(5) be in the most high-grade (namely switch K1, switch K2 line bag all charged) time, if output voltage still < 342V, be failure to actuate (namely maintaining the former position of the switch), perform step (1)；
(6) when being in deep low gear (namely switch K1, switch K2 line bag all not charged), if output voltage is still > 407V, is failure to actuate, maintains the former position of the switch, perform step (1).
The operation of said method can pass through artificial realization, it is also possible to is undertaken automatically controlling realization by each several part connects control device (such as microprocessor, single-chip microcomputer).
