1. Reasons for using cabinet products
In the half century since the founding of the People's Republic of China, China's power industry has achieved rapid development, with an average annual growth rate of more than 10%. In particular, since the 1990s, the goal of doubling the total installed capacity in 8 years has been achieved, and finally the last 50 years of continuous power shortages have been alleviated. However, at the same time, the bottlenecks of transmission and distribution have become increasingly apparent and the power grid structure is weak. The power distribution capacity of urban and rural power grids is insufficient and severely overloaded, and cannot meet the needs of urban and rural industrial and agricultural production and residential electricity consumption growth. To this end, the state has implemented a more active fiscal policy and invested a lot of funds to promote the Rural power grid construction and transformation projects include infrastructure and construction to promote the development of the national economy.
In order to meet the needs of power grid construction and transformation, promote the technical progress of China ’s low-voltage and high-voltage power distribution industry, and accelerate the development of high- and low-voltage power distribution complete switchgear, the Ministry of Energy, the Ministry of Machinery, the Electric Power Bureau and various power design institutes In the electrical control industry, the research and development of various types of transmission and distribution equipment has the characteristics of protection, safety, convenience, high degree of automation, and strong practical reliability, and also reflects the achievements of China's high-voltage and low-voltage power distribution facilities.
2.Classification and types of cabinet products
Our company specializes in producing GGD, GCK, GCS. High and low voltage complete cabinets such as box transformers.
3. Structural characteristics of related types of products
In view of the wide variety of cabinets, several typical cabinet structures are exemplified:
① The cabinet of GGD type AC low-voltage power distribution cabinet adopts the form of general purpose cabinet. The frame is made of 8MF cold-rolled section steel by local welding and assembly. The components of the cabinet are designed according to the module principle and have 20 mold mounting holes. The universal coefficient is high. According to the requirements of modern industrial product modeling design, the golden section ratio method is used to design the appearance of the cabinet and the partition size of each part, so that the whole cabinet is beautiful and new, the cabinets are easy to connect, install and disassemble, and the protection level is IP30.
② The main frame of the GCS cabinet device adopts 8MF section steel, and the frame adopts two structural forms of assembly and partial welding. There are mounting module holes E = 20mm on the main frame.
The functional rooms of the device are strictly separated, and the compartments are mainly divided into functional unit rooms, busbar rooms, cable rooms, and the functions of each unit are relatively independent.
With drawer as the main body, it has both pull-out type and fixed type, which can be mixed and combined. The device is designed according to three-phase five-wire system and three-phase four-wire system. The protection level of the cabinet is IP30 and IP40.
③MNS is composed of two parts: a fixed cabinet and an extractable part (ie, a handcart). The shell and the partition of each functional unit are made of aluminum-zinc plate and assembled. The enclosure's protection grade is IP4X, When the circuit breaker room door is opened, the protection level is IP2X. The cabinet has the functions of rack room inlet and outlet wires, cable inlet and outlet wires, and left-right communication. The cabinet can be installed against the wall.
The cabinet is composed of four parts: the front cabinet, the rear cabinet, the instrument room, and the pressure relief device. These four parts are assembled independently and then joined together. Because the shell and partition of each part are made of aluminum-zinc plate and processed by CNC machine tools and bent, the assembled switch cabinet can maintain the size. Unity. It has a strong anti-corrosion and oxidation resistance, and has higher mechanical strength than equivalent steel plates. The switch cabinet is separated from the car room, bus room, cable room, relay instrument room, and the shell of the first unit has independent grounding. The doors are electrostatically sprayed to make their surfaces resistant to impact, corrosion and aesthetic appearance.
