KUC321AE ABB 励磁系统控制单元电源模块

KUC321AE ABB 励磁系统控制单元电源模块

产品介绍：

一、适用范围

1．本产品适用于化工、海上钻井平台、冶金、医药、轻工、纺织、食品、生物工程、航天航空工程以及等爆炸性气体或粉尘环境中，作为三相四线制（380v/220v）交流低压电器配电系统供电或对检测仪表、分析仪表、监视器、微电脑触摸屏、大功率变频器等元件的监测和控制。

2．适用于1区、2区危险场所。

3．适用于iia、iib、iic类，温度组别为t1-t4的爆炸性气体环境。

4．户内、户外安装。

二、防爆原理

采用介质隔离点燃源的防爆措施。即：把用户所用的电器元件安装在一个充满正压洁净气体的柜体内，使外部环境中易燃易爆的混合性气体无法接触到电器元件在正常工作时所产生的电火花或危险温度，从而达到电器防爆的目的。

三、产品特点

1．本产品主要由柜体、自控系统、布气系统、报警系统、配电系统组成；柜体由正压腔和副腔组成，正压腔内装用户的配电系统元件，副腔内装自控系统。

2．柜式产品采用ggd柜架，主副盘为左右结构，电缆沟座式安装，下进线、前门操作，后门检修。

3．箱式产品采用钢板焊接结构，主、副盘为上下结构，挂式安装，下进线、前门操作和检修。

4．琴台式产品采用钢板折叠焊接成型，主、副盘为前后结构，座式安装，下进线、琴台操作，后门检修。

5．按进气方式分为通风型和补偿型。通风型为不间断连续供气，正压腔内装元件的工作热量可随气路带走，具有很好的散热功能，适用于解决大功率防爆变频器的散热问题；补偿型为间断性供气，正压腔要有良好的密封性，确保耗气量小。

6．用户须提供气源，要求为：净化空气或氮气，气源压为为：0.2～0.8mpa；通常用户现场的仪表风均可满足要求。

Product Introduction:

Scope of application

1. This product is suitable for chemical industry, offshore drilling platform, metallurgy, medicine, light industry, textile, food, biological engineering, aerospace engineering and other explosive gas or dust environment. As a three-phase four-wire system (380v/220v) AC low-voltage electrical distribution system power supply or to the detection instrument, analysis instrument, monitor, microcomputer touch screen, high-power inverter and other components monitoring and control.

2. Applicable to dangerous places in Zone 1 and Zone 2.

3. Applicable to iia, iib, iic class, temperature group t1-t4 explosive gas environment.

4. Indoor and outdoor installation.

Second, explosion-proof principle

Explosion-proof measures for dielectric isolation of ignition source are adopted. That is, the electrical components used by the user are installed in a cabinet full of positive pressure clean gas, so that the flammable and explosive mixed gases in the external environment can not contact the electrical components generated in the normal operation of the spark or dangerous temperature, so as to achieve the purpose of explosion-proof electrical appliances.

Third, product characteristics

1. This product is mainly composed of cabinet, automatic control system, gas distribution system, alarm system, power distribution system; The cabinet is composed of a positive pressure chamber and a sub-chamber. The positive pressure chamber is equipped with the user's power distribution system components, and the sub-chamber is equipped with the automatic control system.

2. Cabinet products use ggd cabinet rack, the main and auxiliary disks are left and right structure, cable tray installation, down line, front door operation, rear door maintenance.

3. Box-type products adopt steel plate welding structure, the main and auxiliary plates are upper and lower structure, hanging installation, down line, front door operation and maintenance.

4. Instrument platform products are made of steel plate folding and welding molding, the main and auxiliary disks are front and rear structure, seat installation, down line, instrument platform operation, rear door maintenance.

5. According to the intake mode, it is divided into ventilation type and compensation type. The ventilation type is uninterrupted continuous gas supply, and the working heat of the components installed in the positive pressure chamber can be carried away with the gas path, which has a good heat dissipation function, and is suitable for solving the heat dissipation problem of high-power explosion-proof inverter. The compensation type is intermittent gas supply, and the positive pressure chamber should have good sealing to ensure small air consumption.

6. The user must provide the air source, the requirements are: purified air or nitrogen, the air source pressure is: 0.2 ~ 0.8mpa; Usually, the instrument wind at the user's site can meet the requirements.
