Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Embodiment one
As shown in Figure 1, a kind of air conditioner power source system with current-limiting apparatus, including air-conditioning transformer 1, air conditioner power source case 2
Pass through current-limiting apparatus 3 and vehicle tractive transformer (not shown) with the input terminal of current-limiting apparatus 3, the air-conditioning transformer 1
Connection, input power are single-phase AC400V, and the output end of air-conditioning transformer 1 is connect with air conditioner power source case 2, the air conditioner power source case
2 have multiple power supply interfaces, and the effect of air-conditioning transformer 1 and air conditioner power source case 2 is that single-phase AC400V power supply is converted to three-phase
It is exported after AC400V, AC40V and AC37.5V, for powering for air-conditioning.
The current-limiting apparatus 3 includes that contactor CHK, the contactor CHK has the first normally opened contact, normally opened with first
The current-limiting resistance R of contact shunt, the current-limiting resistance R connect with air-conditioning transformer 1, and in the first normally opened contact closure, institute
Current-limiting resistance R is stated to be short-circuited.The coil of the contactor CHK is connect with air conditioner power source case 2, in the output end of air-conditioning transformer 1
When exporting electric current, the coil of the contactor CHK is powered, and controls the first normally opened contact closure, opens in this way in air-conditioning transformer 1
When dynamic, current-limiting resistance R plays the role of partial pressure, limits the starting current of air-conditioning transformer 1 in the reasonable scope, avoids vehicle
When crossing that air-conditioning transformer 1 starts after split-phase, the excessive problem of starting current, after the output end of air-conditioning transformer 1 exports electric current,
The coil of contactor CHK, which is initially powered up, is closed the first normally opened contact, and current-limiting resistance R is short-circuited, the partial pressure that do not recur effect, air-conditioning
Transformer 1 can be with rated power operation.
Preferably, the current-limiting resistance R is a pair, and to be connected in parallel, two resistance R can play shunting function.
Preferably, the input terminal of the air-conditioning transformer 1 and output end are also in series with closing switch respectively, in emergency
Under, the electric current input or output of air-conditioning transformer 1 can be directly cut off by closing switch.
