specific Embodiment approach

[0016] The preferred embodiment of the solid insulation vacuum ring network cabinet of the present invention is:

[0017] It includes a high-voltage compartment, which is equipped with an isolation knife switch unit, a vacuum load switch unit, and a fuse unit. The main busbar is connected to the outgoing cable through the isolation knife switch unit, the vacuum load switch unit, and the fuse unit in sequence. The vacuum load switch unit is sealed and insulated with epoxy resin.

[0018] It also includes a mechanism box, which is equipped with an isolation knife switch operating mechanism and a vacuum load switch operating mechanism, of which:

[0019] The isolating knife switch operating mechanism is connected with the knife switch of the isolating knife switch unit, and is used to drive the up and down movement of the knife switch to realize the opening and closing of the isolating knife switch unit.

[0020] Specifically, it can be that the isolation knife switch operating ...

specific Embodiment

[0031] Specific examples, such as figure 2 Shown:

[0032] It includes a high-voltage compartment 1 and a mechanism box 4. The high-voltage compartment 1 is provided with an isolation knife switch unit 2, a vacuum load switch unit 3, and a fuse unit 9. The isolation switch unit 2 plays the role of isolation, grounding and bus connection, the load switch unit 3 plays the role of breaking the load current, and the fuse unit 9 plays the role of short circuit protection.

[0033] It also includes a vacuum load switch operating mechanism 5, an isolation knife switch operating mechanism 6, an outgoing cable 8, an outgoing unit grounding device 7, etc., and the outgoing unit grounding device 7 plays the role of grounding the outgoing cable.

[0034] In the working state, the high-voltage current passes through the main bus to the isolation switch unit 2, then from the isolation switch unit 2 to the vacuum load switch unit 3, then from the vacuum load switch unit 3 to the fuse unit ...

Abstract

The present invention discloses a solid isolated vacuum ring main unit, comprising a high-pressure compartment, wherein the high-pressure compartment is provided with an isolation switch unit, a vacuum load switch unit and a fuse unit. A main bus-bar is connected with an outlet cable through the isolation switch unit, the vacuum load switch unit and the fuse unit. The vacuum load switch unit is fixedly sealed and isolated by adopting epoxy resin. The solid isolated vacuum ring main unit further comprises a mechanism box, wherein the mechanism box is provided with an isolation switch operatingmechanism and a vacuum load switch operating mechanism; the isolation switch operating mechanism is connected with an isolator of the isolation switch unit for driving the isolator to move up and down, thereby realizing the separation and combination of the isolation switch unit. The solid isolated vacuum ring main unit has the advantages of small volume, is suitable for various indoor and outdoor bad operating environments and is nontoxic and pollution-free; the ring main unit body does not need sealing, and does not have the dangerous of air leakage.

Description

technical field [0001] The invention relates to a city power supply network ring network cabinet, in particular to a solid insulation vacuum ring network cabinet. Background technique [0002] The current urban power supply network mainly adopts the ring network power supply mode. The ring network power supply mode can improve the reliability of power supply. Users can obtain power from both ends to reduce the power outage area of ​​the accident; the ring network cabinet is the medium voltage equipment used for ring network power supply , the core part of which is the load switch and load switch-fuse combination appliance, which has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. [0003] There are two types of ring network cabinets in the prior art: air insulation and SF6 gas insulation: [0004] The air-insulated ring network cabinet is composed of a low-voltage compartment and a high-vo...
