Switchgear is a key equipment in the power system, mainly used for the distribution and control of electric energy. The functional cabinets of the switchgear mainly include incoming cabinet, outgoing cabinet, busbar cabinet, isolation cabinet, metering cabinet, PT cabinet and capacitor cabinet. Now let's briefly introduce their respective functions, so that we can make a choice after understanding them clearly.

Speaking of current transformers, I believe everyone is familiar with them. Current transformers are widely used in power systems and can always be seen in various switch cabinets and distribution cabinets.Its main function is to convert high values into low values, which is suitable for measuring instruments and relays. The commonly used secondary rated current is 5A. https://www.hbianelectric.com/oil-immersed-transformer-series/

The kW power consumption of a 1000kVA transformer is not a fixed value. It is affected by power factor, load rate, type of electrical equipment, environmental factors, etc. In actual power planning and application, these factors need to be fully considered.

Typical case: A factory extended the life of its transformer from 15 years to 25 years and reduced its operation and maintenance costs by 40% by installing an intelligent temperature control system and quarterly dust removal.

At present, the inflatable cabinet mainly refers to the primary distribution switchgear, that is, used for main power distribution, with a rated current of 630-4000A and a short-time withstand current of 25-50kA. Compared with the air-insulated switchgear, the size of the inflatable cabinet is greatly reduced and is not affected by the environment.

Specifically, after adding a capacitor to the AC circuit, it can offset the reverse force (reactive power) generated by some devices (such as coils), thereby better synchronizing the current and voltage, reducing power waste and improving power efficiency.
