The ZH series open-type combined electrical apparatus is an outdoor device composed of an isolating switch, current transformer, or cable head, featuring a compact structure, simplicity, and ease of maintenance. It is suitable for large and medium-sized power stations, significantly reducing the footprint and space required, thereby lowering project costs. This product can be based on a double-column horizontal telescopic clamp-type isolating switch, with the static end replaced by a transformer, or based on a three-column horizontal flip-type isolating switch, with one side's static contact pillar replaced by a transformer, while the transformer's head is equipped with the isolating switch's static contact, integrating the transformer and isolating switch into a single unit. Additionally, to achieve smart grid functionality and facilitate pre-system monitoring and maintenance as well as post-fault analysis, the ZH series open-type combined electrical apparatus can be upgraded to a "digital, fiber-optic, and intelligent" system through data signal processing technology, becoming an intelligent combined electrical apparatus.

Product Features:

It can be combined with CT, ECT, ECVT transformers, or other transformers of any height produced by mainstream domestic manufacturers. The static end base adopts a targeted design, reserving sufficient installation space for the transformer, facilitating on-site installation.

The main isolating switch part has reliable performance and is easy to install. It can be used in extremely harsh environments and has been operating in the domestic power grid for many years.

The transformer part can be equipped with a grounding switch and can achieve mechanical interlocking with the isolating switch. The interlocking device features a simple structure, direct operation, and high mechanical strength.

Temperature detection units and clamping force monitoring units can be installed in the contact area of the dynamic and static contacts. Using wireless communication, real-time online monitoring can be achieved, enabling intelligent control and reducing the occurrence of accidents.
