Description
Technical Field
The utility model belongs to the technical field of electrical equipment, and particularly relates to a time delay starting device of a ground power supply vehicle.
Background
The ground power supply vehicle is a key device for supplying power to various devices on the plane when the plane stays on the ground. When the ground power supply vehicle is used, particularly when a test flight station performs a flight work, the ground power supply vehicle can be started only after a power switch of an airplane is closed. However, it is found through inspection that the ground power supply vehicle used in the current station generates surge voltage within the started 5S, and at the moment, because the onboard power switch is closed, the risk of burning the onboard equipment exists.
Disclosure of Invention
The technical problem solved by the utility model is as follows: in order to solve the problem that surge voltage can be generated in the 5S of starting of the conventional ground power supply vehicle, and at the moment, the risk of burning airborne equipment exists because an onboard power switch is closed, the delay starting device of the ground power supply vehicle is provided.
The technical scheme of the utility model is as follows: a delay starting device of a ground power supply vehicle comprises a fuse FU, a time relay JS and an intermediate relay KA;
a coil of the intermediate relay KA and a normally open contact SJ of the time relay are connected in series and then connected in parallel with a coil of the time relay JS, and then connected in series with the fuse FU at the input end of the ground power supply vehicle; the normally open contacts KA1, KA2 and KA3 of the intermediate relay KA are located at the output end of a voltage conversion circuit of the ground power supply vehicle and are connected with the airborne circuit through cables.
The further technical scheme of the utility model is as follows: and the time for the normally open contact SJ of the time relay to be closed in a delayed manner is at least 5 seconds.
The further technical scheme of the utility model is as follows: fuse FU is connected in series at the rear end of AC contactor KM.
The further technical scheme of the utility model is as follows: after time relay JS coil received power, time relay normally open contact SJ delay was closed, and auxiliary relay KA received power, and auxiliary relay normally open contact KA1, KA2, KA3 were closed, through the stable direct current of control voltage conversion circuit output.
Effects of the utility model
The utility model has the technical effects that: the ground power supply vehicle has the advantages of being reasonable in design, capable of guaranteeing normal and stable operation of the ground power supply vehicle through the fuse FU, the time relay JS and the intermediate relay KA, simple in circuit, free of too many components, simple and easy to operate, low in raw material investment, low in labor cost, high in economic benefit and the like.

Detailed Description
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.
Referring to fig. 1, a delay starting device of a ground power supply vehicle comprises components such as a fuse FU, a time relay JS and an intermediate relay KA. On the basis of original control circuit, install time relay JS, auxiliary relay KA additional, utilize time relay's time delay effect, surge voltage that produces in the twinkling of an eye when the normally open contact control ground power supply car through auxiliary relay starts avoids because the burning out of the too high aircraft airborne equipment that causes of voltage.
The structure is added with the fuse, and plays roles in overload and short circuit protection; a time relay is added to carry out delay control on the starting time of the ground power supply vehicle; and an intermediate relay is added, and a voltage conversion circuit of the ground power supply vehicle is controlled by utilizing the multi-contact principle of the intermediate relay.
This circuit is on original control circuit's basis, through ac contactor KM series time relay JS, the coil is got electric back, and time relay normally open contact SJ delay is closed, and auxiliary relay KA gets electric, and auxiliary relay normally open contact KA1, KA2, KA3 are closed, through the stable DC voltage of control voltage conversion circuit output.
