The compositions such as JCE1005-FS current sensors, wind turbine, active C rowbar.
Grid-connection cabinet：Be mainly used for current transformer connect with generator system and power grid control, the acquisition of number control signal with
And the configuration of secondary circuit.Grid-connection cabinet is mainly by breaker, contactor, signal collecting element, UPS, heater, signaling interface portion
Grade composition.
It needs to be attached by copper bar between rotor-side power module and reactor, existing copper bar is connected as in power
A vertical copper bar is directly connected between module terminals and reactor busbar, by the both ends of copper bar respectively with power module end
Son and reactor busbar are fixed by bolt.Currently, since equipment is improved, with three output ends of rotor-side power module
The mounting surface for the copper bar that son is connected is vertically arranged, and the mounting surface of reactor busbar is horizontally disposed.As a result, if two
Still hard copper bar is used to connect between person, then be easy to cause the deformation of copper bar during the work time, influence rotor-side power module
Connective stability between reactor and reliability cause the work of wind-power electricity generation frequency conversion device to occur abnormal.
