Problems solved by technology

[0003] However, in the case of an oil-immersed reactor, due to the temperature of the cooling oil in the oil circuit and the deterioration of the cooling oil in the oil circuit, the pressure is too high, and the failure of the oil pump of the oil-immersed reactor causes the oil in the oil circuit. The flow of the cooling oil is unstable, etc., resulting in frequent occurrence of unstable operation of the oil-immersed reactor

Embodiment Construction

[0024] The oil-immersed reactor 1 of the present invention is applied to locomotives. The oil-immersed reactor 1 may include: a casing 10, which forms the appearance of the oil-immersed reactor and protects the internal components of the oil-immersed reactor; an oil circuit 11, for cooling oil to flow; wiring The terminal 12 is electrically connected to the main circuit of the locomotive; the radiator 13 is arranged on one side of the casing 10 ; the oil pump 14 is arranged on the casing 10 on the side opposite to the radiator 13 .

[0025] The oil-immersed reactor may also include a temperature sensor 15 . The temperature sensor 15 can be disposed on the casing 10 . When the temperature of the cooling oil inside the oil-immersed reactor 1 reaches a certain temperature (for example, 95°C, 105°C), the maximum output power of the locomotive decreases linearly. For example, when the temperature of the cooling oil reaches 95°C, the maximum output power of the locomotive decrease...

Abstract

The invention provides an oil-immersed reactor and a locomotive with the oil-immersed reactor. The oil-immersed reactor can comprises: a casing forming the appearance of the oil-immersed reactor and protecting members inside the oil-immersed reactor; an oil pump for sucking cooling oil; an oil path for flowing of the cooling oil; and a temperature sensor arranged on the casing and used for detecting the temperature of the cooling oil in the oil path.

Description

technical field [0001] The invention relates to the field of reactors, in particular to reactors arranged on locomotives. Background technique [0002] At present, the reactors used in locomotives mainly include dry (air-cooled) reactors and oil-immersed reactors. In the DC power supply system, the reactor and capacitor in the main circuit of the locomotive together form the main circuit filter. The reactor has the function of "passing DC and blocking AC". , will filter out higher frequency interference signals, so the filter can weaken the impact of grid voltage fluctuations on the inverter, and at the same time limit the flow of load harmonic currents to the grid, reduce the interference of harmonic currents to electronic instruments, and prevent short circuits can limit the rate of rise of the current. [0003] However, in the case of an oil-immersed reactor, due to the temperature of the cooling oil in the oil circuit and the deterioration of the cooling oil in the oil...
