The utility model content
The technical problem that the utility model will solve and the technical assignment of proposition are that the prior art scheme is improved and improved, and traction power supply single-phase voltage regulating isolating transformer is provided, and to reach the inhibition electromagnetic interference, purify the purpose of electrical network.For this reason, the utility model is taked following technical scheme.
Traction power supply single-phase voltage regulating isolating transformer; Comprise fuel tank, be located at the device body in the fuel tank; Described device body comprises that iron core, concentric locking collar are connected to the isolating transformer former limit winding and the isolating transformer secondary winding of iron core, is characterized in that: the equal turn numbers of isolating transformer former limit winding and isolating transformer secondary winding.Set up an isolating transformer between main transformer and the contact line, suppress electromagnetic interference, purify electrical network.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
The former limit of isolating transformer winding and traction power supply the secondary winding of main transformer link to each other, isolating transformer secondary winding and traction power supply contact line be connected.
Be equipped with ring shaped oil passage between described isolating transformer former limit winding and the isolating transformer secondary winding and between isolating transformer secondary winding and the iron core.Guaranteed the radiating condition of transformer.
The fuel tank outside is provided with radiator and oil conservator.
The fuel tank outside is provided with the sleeve pipe that is used for wiring and makes things convenient for wiring.
Beneficial effect:
1, anti-interference effect: utilize the big characteristics of high-frequency loss of its iron core, import control loop into thereby suppress the high frequency clutter;
2, impedance conversion effect: increase system impedance, make cooperations easily such as protective device;
3, the effect of systems stabilisation voltage: when heavy load equipment locomotive through out-of-date, reduce influence to system voltage;
4, reduce short circuit current: when load side is short-circuited accident, the short circuit current of restriction system;
5, electrical isolation effect: the protection device security, isolate dangerous voltage.
The coupling of isolating transformer output input capacitance is little, to owing to lightning, discharges, and electrical network switches, and the interference that the dry sound of other electrical network causes has more inhibitory action.
