HVDC Cooling System
With the increasing demand of electricity and the imbalance of distribution of energy resources and electricity consumption, the distance and large scale transmission has become the necessary way to optimize the allocation of power resources. DC power transmission system is an important way to make a strong power grid backbone network and distance power transmission. Thyristor valve is the core equipment of HVDC power transmission project, and is the core function unit of AC and DC power conversion. The safe and stable operation of the cooling system for thyristor valve is a necessary precondition and a solid foundation for the safe and stable operation of the thyristor valve.
Henan Jingrui DC transmission valve cooling system has a market share of 50%. The self-developed ZLSS, ZLSF, ZLSX series valve cooling system can flexibly and efficiently face and solve the cooling and heat dissipation problem of the converter valve in different environments and geographical conditions. (Below) All forms of converter valve cooling in domestic and international DC transmission projects can also be used for converter valve cooling in flexible DC transmission projects. Different series of cooling systems have the following characteristics: key equipment and control systems are redundantly configured, while using high-reliability well-known brand products, energy and water saving, high reliability, high redundancy, low maintenance, and applicability Powerful, equipped with a sound and perfect protection function and a control system with strong electromagnetic interference capability, a single component failure will not affect the normal operation of the equipment.
