FKJ-A1型离网风光互补/风力发电机控制器

fkj型产品特性

◆fkj-a1型、fkj-a2型控制器，采用多路三相卸荷控制。

◆三相卸荷总功率大于风力发电机额定功率的220%。第一路三相卸荷功率是风力发电机额定功率的80-，当超出第一路卸荷功率范围时，第二路三相卸荷立即自动启动，保证风力发电整套系统安全运行。

◆在蓄电池脱节、损坏情况下，三相卸荷自动启动。防止风力发电机空转、飞车事故发生。

◆具有蓄电池防反接保护，蓄电池防脱节保护，蓄电池防损坏保护。

◆蓄电池过充保护。当蓄电池充满时（蓄电池电压达到额定电压125%），控制器将自动三相卸荷，停止对蓄电池充电。

◆蓄电池自动恢复充电功能。当蓄电池电压降至额定电压108%时，卸荷器停止三相卸荷，自动恢复对蓄电池充电。

◆控制器根据风力发电机的种类，可增加机械偏航控制、机械折尾控制、机械或液压、气压、电磁，等多种制动控制功能。

◆led灯状态指示。风力发电机、太阳能电池板、蓄电池、控制器工作状态一目了然。

◆电流表、电压表指示。指示蓄电池充电电流及蓄电池电压。

◆控制器具有手动三相卸荷开关，用户可根据情况使用。.使用此开关，风力发电机将强制性三相卸荷。

fkj model product characteristics

◆the product can be manufactured in accordance with either jb/t6939.1-2004 industrial standard, gb/t 19115.1-2003 national standard or users’ technical requirements.

◆fkj-a1 and fkj-a2 controllers adopt multiple-line three-phase load discharging control.

◆the total power of three-phase load discharging is 220% larger than the rated power of the wind turbine generator. the three-phase load discharging power of the first line is 80- of the rated power of the wind turbine generator; in case of exceeding the scope of the first line load discharging power, the three-phase load discharging of the second line will automatically start to ensure safe operation of the overall wind turbine generation system.

◆under the circumstances of decoupling and damage of the battery, the three-phase load discharging will automatically start to avoid the idle run of the wind turbine generator and the occurrence of runaway accident.

◆ it hasreverse connection, anti-decoupling and damage-resisting protection of the battery.

◆over-charging protection of the battery: when the battery is full (the battery pressure reaching 125% of the rated pressure), the controller will automatically carry out three-phase load discharging to stop charging the battery.

◆auto recovery of battery charging:when the battery pressure reduces to 108% of the rated pressure, the load discharger will stop three-phase load discharging to automatically recover battery charging.

◆according to the category of the wind turbine generator, the controller can be additionally equipped with mechanical yawing, swing-tai, mechanical or hydraulic, pneumatic, magnetic and other brake functions.

◆led status indication: clearly present the working status of the wind turbine generator, solar panel, battery and controller.

◆ammeter and voltmeter indication: indicate the charging current and voltage of the battery.

◆the controller is equipped with manual three-phase load discharging switch; the user may use it according to actual circumstances. when using this switch, the wind turbine generator will forcibly carry out three-phase load discharging.
