Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Please refer to fig. 1.

The embodiment provides a power generation car low-voltage outgoing cable lengthening connecting device, which comprises a power distribution cabinet 12, a molded case leakage circuit breaker 14 is installed in the power distribution cabinet 12, and four incoming line wiring terminals 13 and four outgoing line wiring terminals 15 are arranged on the molded case leakage circuit breaker 14.

The four incoming line wiring terminals 13 are respectively connected with a power generation car power supply cable 16 directly or through copper wire lugs.

Specifically, the incoming line terminal 13 is connected to the generator car through the generator car power supply cable quick connector 10 on the generator car power supply cable 16. Specifically, one end of the power generation car power supply cable 16 can be directly connected with the incoming line wiring terminal 13, and can also be connected with the incoming line wiring terminal 13 by arranging a copper wire lug.

The four outgoing line connecting terminals 15 are connected with the user side through extension cables 11 respectively.

The rated current of the molded case leakage breaker 14 is 800A.

The power distribution cabinet 12 is made of stainless steel.

The power distribution cabinet 12 is in a cuboid shape, and the protection grade of the power distribution cabinet 12 is IP 65.

IP is a code number used internationally to identify the protection grade, the IP grade is composed of two numbers, the first number represents dustproof, the second number represents waterproof, and the larger the number is, the better the protection grade is.

Thus, numeral 6 indicates complete prevention of dust ingress, and numeral 5 indicates no effect of any angle of low pressure injection.

The four outgoing line wiring terminals 15 are respectively connected with extension cables 11, and one ends, far away from the outgoing line wiring terminals 15, of the extension cables 11 are used for being connected to a user side. Therefore, when the low-voltage outgoing cable lengthening connecting device for the generator car is used, the power supply cable 16 of the generator car is connected into the incoming line wiring terminal 13, and power is transmitted out through the molded case leakage breaker 14. Specifically, one end of the extension cable 11 is connected into the outgoing line connecting terminal 15, and the other end of the extension cable 11 is connected into the user side, so that the cable can be quickly lengthened, and the power supply length of the power generation car power supply cable 16 can be prolonged.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "including," and "having" are intended to be inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

In contrast, when an element or layer is referred to as being "directly on … …," "directly engaged with … …," "directly connected to" or "directly coupled to" another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship of elements should be interpreted in a similar manner (e.g., "between … …" and "directly between … …", "adjacent" and "directly adjacent", etc.). As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region or section from another element, component, region or section. Unless clearly indicated by the context, use of terms such as the terms "first," "second," and other numerical values herein does not imply a sequence or order. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

Spatially relative terms may be intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below … …" can encompass both an orientation of facing upward and downward. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
