Description
The use of frequency converters in enterprises is growing every year. The main reason is ease of management and automation of the technological process. In addition, lower energy costs help recoup implementation costs.
Frequency converters in water supply allow you to adapt to changing parameters – to ensure constant pressure in the network (mains water supply), stable flow (sewage) or maintaining a differential (heating systems).
To regulate the boiler feed pumps, high-voltage, powerful frequency converters are required. The leaders of the Russian market are Russian-made frequency converters from the ChEAZ and VNIIR companies (Cheboksary). 70 years of experience in the electrical equipment industry and the implementation of all the most advanced technologies in the field of power conversion and automation systems allows these companies to create frequency converters at the level or even higher than the level of the world’s best manufacturers.
The production of low-voltage converters in Russia does not make economic sense, because the cost of conveyor production of low-voltage converters of global brands in China is minimized.
The main challenge when supplying low-voltage frequency converters for pumps is the development of a control station. To select the equipment correctly, our engineers take into account all design features, options, control logic, implementation of protection and automation, and much more. A correctly developed technical specification for production is 90% of the success of implementing a frequency converter into the drive of a pumping unit.
Frequency converters CHEAZ
CHEAZ is a leading Russian electrical equipment plant with a long history. The presence of its own production base, a testing shop with a load converter and a reactor, allowing testing of drives up to 17.5 MW, 3 BMZ assembly shops, in-house development of IGBT transistors and drivers – all this allows the ChEAZ company to implement the most technically complex and non-standard projects. The CHEAZ company is a supplier to the largest Russian companies, supplies its products to the army and navy, and is approved by RMRS.
VNIIR frequency converters
VNIIR – The VNIIR company is part of the ABS Electro holding. Historically, VNIIR was a scientific institute and developer for the Cheboksary Electrical Equipment Plant. After perestroika, VNIIR separated and became part of ABS Electro. The company has a large reference supply of frequency converters, soft starters and complex integrated electric drive systems. The VNIIR company has a large staff of specialized specialists who can complete a project even with the most extraordinary customer requirements. An established network of partners and suppliers allows VNIIR to select the optimal equipment based on price/quality criteria.
