In the description of the present invention, if there are first and second descriptions for distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the precedence of the indicated technical features.

In the present invention, unless otherwise explicitly defined, the terms "set," "mounted," "connected," and the like are to be understood in a broad sense, and may be directly connected or indirectly connected through an intermediate medium, for example; 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 technical skill in the art can reasonably determine the specific meaning of the above words in the present invention by combining the specific contents of the technical solution.

Referring to fig. 1 to 4, the embodiment of the present invention provides a power supply, grounding and cross-region connection integrated switch cabinet for a contact network, which includes a housing 100, a three-position isolating switch 200 and a cross-region isolating switch 300.

A partition is provided in the housing 100, the partition divides the inner cavity of the housing 100 into a high pressure chamber 110 and a low pressure chamber 150, and the three-position disconnecting switch 200 and the across disconnecting switch 300 are provided in the high pressure chamber 110.

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.

The manual control mechanism 400 may be a gear transmission structure with a handle.

Referring to fig. 2, when the first blade brake contact 230 is biased and abuts the first power supply contact 210, it is possible to realize that the first power supply cable supplies power to the overhead line system.

When the first knife brake contact 230 is biased and abuts against the grounding contact 220, the charge of the contact net can be led out to the ground, so that the safety of the maintainer is ensured.

Because the first knife brake contact 230 can only move between the first power supply contact 210 and the grounding contact 220, the uniqueness of the power supply state and the grounding state of the contact net can be ensured without electrical linkage, and the reliability is strong.

The hand-off disconnector 300 is provided with a second power supply contact 310 and a second disconnecting link contact 320, the second power supply contact 310 being electrically connected to an external second power supply cable, and the second disconnecting link contact 320 being electrically connected to an external catenary.

When the first power supply cable fails to supply power to the overhead contact system due to a failure, the second disconnecting link contact 320 is biased to abut against the second power supply contact 310, so that power supply to the overhead contact system is performed over a region.

In order to easily observe the states of the three-position isolator 200 and the handoff isolator 300, the housing 100 is provided with a first observation window 130 and a second observation window 140, the first observation window 130 is provided corresponding to the three-position isolator 200, and the second observation window 140 is provided corresponding to the handoff isolator 300.

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.
