High and low voltage control cabinet using environmental requirements on the use of high and low voltage control cabinet for environmental requirements: 1 the ambient temperature does not exceed 40 ℃, Zhengzhou high and low voltage power distribution, minimum ambient air temperature is -5 ℃, -15 ℃, -. 25 ℃. 2. The altitude does not exceed 1000M. 3. Temperature: The average value measured over 24h and the relative humidity does not exceed 95%; taking into account changes in temperature, high and low voltage power distribution equipment dealers, allowing produce moderate condensation. The ambient air is not significantly polluted by dust, smoke, corrosive or flammable gases and steam, salt spray and pollution. High and low voltage control cabinet which demand is also high voltage frequency counters, high and low voltage equipment chassis cabinets environmental requirements. High and low voltage control cabinet is to put some kind of switch circuit breaker protection device integrally assembled electrical equipment. Currently popular on the market high and low voltage control cabinet (low voltage switch cabinet) many models, there is GGD type, GCK type, GCS type, MNS type, MCS-type low-voltage distribution system consists of distribution substation (usually the grid reduced transmission voltage distribution voltage), high voltage distribution lines (ie more than 1 kV voltage), distribution transformers, low-voltage distribution lines (1 kilovolt voltage) and the corresponding control and protection equipment. 1 High and low voltage power distribution system introduced 1. Pressure Power Supply System 1) system definition and composition of hypertension is a relative concept, high prices and low voltage power distribution equipment in the field of posts and telecommunications, we commonly refer to is the 10KV high voltage power supply (small areas will be used 35KV). Our own high voltage power supply system into the line of authority is generally expected to be completed, lightning protection, measuring, metering, qualify, contact and other functions. Some of these functions do not have to use a separate cabinet, such as incoming and lightning protection, measurement and lightning, etc., are often installed in the same cabinet to save space and investment. In addition, the capacity of the station is small (400KVA or less), high and low voltage power distribution equipment company in Henan, according to state regulations, you can not configure the high-pressure system, and directly into the 10KV power transformer high and low voltage power distribution equipment via drop-Insurance Price | Zhengzhou high and low voltage distribution | By Henan Xi Xi Connaught Electrical and Mechanical and Electrical Equipment Co.
