Abstract
The utility model relates to a charging and limiting circuit, which comprises a resistor R1, an inrush current suppression contactor T1 and a main contactor T2. The main contactor T2 is in parallel connection with the inrush current suppression contactor T1 after being in series connection with the resistor R1. The charging and limiting circuit has the advantage of smaller volume.
Description
(1) technical field
The utility model relates to a kind of charging current limiter circuit, belongs to the power technology field.
(2) background technology
At present, in the conventional charging current limiter circuit, main contactor is serially connected on the major loop, thereby when operate as normal, need this main contactor can bear bigger electric current, generally need bear the above electric current of 200A, cause the main contactor volume bigger thus, be unfavorable for that this charging current limiter circuit application is on miniaturization electrical equipment equipment.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of volume less charging current limiter circuit.
The purpose of this utility model is achieved in that a kind of charging current limiter circuit, and described circuit includes resistance R 1, shoves and suppress contactor T1 and main contactor T2, is in parallel with the inhibition contactor T1 that shoves after described main contactor T2 connects with resistance R 1.
The beneficial effects of the utility model are:
Since with main contactor be connected in the inhibition contactor that shoves after resistance is connected, thereby main contactor only has electric current to pass through when starting, usually the little electric current of only having an appointment about 30A passes through, when operate as normal, the big electric current main contactor of can not flowing through, thereby, only need to be equipped with to bear the needs that the less contactor of current capacity can satisfy operate as normal, and bear the less contactor of electric current, volume is less comparatively speaking, thereby can make whole charging current limiter circuit have smaller volume, conveniently be applied on the miniaturization electrical equipment equipment.
(4) description of drawings
Fig. 1 is the utility model electrical block diagram.
Fig. 2 is conventional charging current limiter circuit.
(5) embodiment
Referring to Fig. 1, the utility model relates to a kind of charging current limiter circuit, include resistance R 1, shove and suppress contactor T1 and main contactor T2, be in parallel with the inhibition contactor T1 that shoves after described main contactor T2 connects with resistance R 1, the circuit after the parallel connection seals on the charge circuit main line.
Claims (1)
1. charging current limiter circuit is characterized in that: described circuit includes resistance R 1, shoves and suppress contactor T1 and main contactor T2, and connect with resistance R 1 back and the inhibition contactor T1 that shoves of described main contactor T2 is in parallel.
