Under the normalsituation in many factories, the air compressor works in non-full loadconditions for a large part of time, as a result, the traditional control ofair compressor will waste the energy, result in inefficient. This article will introducea solution, which adopt INVT inverter to save energy, and supply a complete controlsystem. There is a energy saving result in this article.
In this paper, through introducing INVT GD5000 medium voltage inverter applied to vertical roller mill in the Pakistan, in order to illustrate VFD transformation of the feasibility and economy. Especially it can increase raw milling production, input power factor and other benefits.

The annual output of coal of a coal company of Shanxi Jincheng Anthracite Coal Mining Group is 600,000 tons, the belt conveyor in the coal outlet is driven by two sets 6kV / 710kW asynchronous motors. The enterprise originally adopts soft starters and hydraulic couplers to solve the problem of motor start and speed control, but there are still a lot of drawbacks. Soft starter will produce a large number of harmonics, hydraulic coupling has high failure rate with large maintenance works, and multi-motor drive is difficult to adopt liquid coupling to solve the power balance problem between two motors.
In the coking process of a coal chemical enterprise of Shaanxi Haotian Group, the gas pressure fan (Roots blower) is driven by a 10kV / 315kW motor, because the gas contains tar, the fan will be adhered with a lot of tar after a long time running with a larger drag torque, and the excess air volume is adjusted by the return valve with serious energy waste.
In this paper，through introducing INVT GD5000 medium voltage inverter applied to Jet condenser for Vacuum Pan in the sugar factory in the Thailand, to illustrate VFD transformation of the feasibility and the significant energy saving.
This paper analyzes the running characteristics of portal crane, and elaborates the selection principle of motor, inverter and its braking mode and the capacity calculation method of the inverter peripheral equipment when CHV190 crane special inverter is used in portal crane speed adjusting, and finally introduces the application case of CHV190 inverter in portal crane.
The traditional hydraulic anti-shake system has a long response time delay, component loss and other issues, seriously troubling the port machine users, with the in-depth promotion of frequency control in the port machine industry, frequency anti-shake system gradually attracts the concern of majority port machine manufacturers and users, and becomes the mainstream of industry applications with its superior torque control performance and solid stability. The rail suspension anti-shake system in this article adopts INVT CHV190 inverter to overcome the lack of hydraulic anti-shake system, which has significantly weaken the spreader swing, marking another major improvement of domestic inverter application in the port machine industry.
