In the description of the present invention, if there are first and second described only for the purpose of distinguishing technical features, it is not understood that relative importance is indicated or implied or that the number of indicated technical features or the precedence of the indicated technical features is implicitly indicated or implied.
In the present invention, unless explicitly defined otherwise, the terms "disposed," "mounted," "connected," and the like are to be understood in a broad sense, and for example, may be directly connected or indirectly connected through an intermediate; can be fixedly connected, can also be detachably connected and can also be integrally formed; may be a mechanical connection; either as communication within the two elements or as an interactive relationship of the two elements. The specific meaning of the above-mentioned words in the present invention can be reasonably determined by those skilled in the art in combination with the detailed contents of the technical solutions.
Referring to fig. 1 to 4, an integrated power supply, grounding and handover device for an overhead line system according to an embodiment of the present invention includes a housing 100, a three-position disconnector 200 and a handover disconnector 300.

Since the high-voltage operating parts generate strong electromagnetic interference during operation, the high-voltage operating parts and the low-voltage operating parts are provided corresponding to the high-voltage chamber 110 and the low-voltage chamber 150, respectively, so that the influence of the electromagnetic interference on the low-voltage operating parts can be advantageously reduced.
The three-position disconnecting switch 200 is provided with a first power supply contact 210, a ground contact 220 and a first knife gate contact 230, wherein the first power supply contact 210 is electrically connected with an external first power supply cable, the ground contact 220 is electrically connected with an external ground cable, and the first knife gate contact 230 is electrically connected with an external contact network.

Wherein, the copper bar has the characteristics that the resistance is low, the degree of buckling is big, consequently, is favorable to reducing the loss of electric energy in transmission process, and in addition, the setting of copper bar can avoid walking the chaotic problem of line.
The housing 100 is further provided with a low pressure chamber 150, and a comprehensive monitoring unit is provided in the low pressure chamber 150.
The comprehensive monitoring unit comprises a detection unit and a communication unit which are electrically connected, the detection unit is electrically connected with the three-station isolating switch 200 to detect voltage information, current information and power information of the three-station isolating switch, and the communication unit can transmit the detected information to an external upper system or terminal, so that remote monitoring of the three-station isolating switch 200 is realized.
Further, the high-voltage chamber 110 is provided with a camera 500 electrically connected to the communication unit, and the camera 500 can capture the states of the three-position disconnecting switch 200 and the hand-off disconnecting switch 300.
