高压多油断路器DW13-35KV 的详细介绍

高压多油断路器DW13-35KV

DW13-35/630、1250、1600型户外高压多油断路器，适用于交流50Hz，额定工作电压为35kV，额定电流为630、1250、1600A的电力系统中，作为工矿企业、发电厂及变电站用电负荷的控制及保护设备使用。

结构特点

断踏器为三相分箱结构，每一相的各种部件固定于油箱盖上。三相油箱盖固定在同一个角钢大支架上。支架的端头装有操动机构，通过拉杆进行三相联动操作，支架上还装有油箱升降机构。

断路器每相两个断口在一个油箱内，负荷电流利用两根电容套管穿过油箱盖引入和引出。电容套管下端固定静触头，灭弧室利用特殊螺纹拧紧于静触头上，两个动触头固定在铝横梁上，由绝缘提升杆带动分合闸运动。

（2）油气分离器

DW13-35型31、5kA的产品油箱盖上装有隔板，将内部隔成两个腔体，隔板上部装有油气分离器。

DW13-35型20kA的产品没有专设油气分离器，但油箱盖上铸有隔板，将内部分隔成上下两个空间，开断时油气通过隔板上的小孔分散进入上部空间，具有一定的油气分离作用。再加上灭弧室等处的改进，在整个开断过程中无明显喷油现象，油位不下降。

（3）排气阀

DW13-35型20kA的产品开断时产生的气体由排气阀活塞上的小孔排出，活塞不移动，DW13-35型31、5kA的产品开断时，铝盖内腔压力稍大于外部，活塞即向右稍许移动而排气，橡皮垫形成活动瓣膜，排气后在扭力弹簧作用下自动复位。

（4）**阀

DW13-35型31、5kA产品的**阀与油气分离器结合在一起，如果由于某种原因使油箱内压力异常增大，将克服弹簧压力推动盖板及长方盒向上运动，在盖板与隔板的管状凸出部分之间形成高约13mm的环形通道，可迅速卸压而保护油箱盖不致损坏。同时，排气阀的活塞移至右端尽头，可迅速排出油气。

（5）套管

电容套管为胶纸电容套管芯充胶结构，套管芯与套管法兰胶粘为一体，瓷套用机械方法压紧，瓷套与套管芯之间灌注专用的套管绝缘胶。

（6）电流互感器

每台断路器可附装6只、9只或12只套管式电流互感器。互感器以电容套管导电杆为一次回路，互感器本身只有环形铁芯及二次回路，电流互感器套在电容套管芯外并固定在油箱盖上。

电流互感器有两种型号，LR-35型供测量用。LRD-35型为B级，供保护用。每一型号的电流互感器均有五种电流比规格。每一种规格的电流互感器有五个接线头，可以获得四种电流比。利用电流互感器引线接线座可以方便的改变电流比。

每台断路器可以附装两种电流互感器，每一种电流互感器的数量为3倍数，两种电流互感器数量之和为6-12只。

（7）操动机构

操动机构控制线路在机构箱左门内侧装有接线标牌，上面也有此线路图，检修时查阅很方便，此线路具有电气联锁及防跳跃性能，分、合闸完成后可自动切断分、合闸电路。

Controller:

The LP Hoying Co. charge / output controller provides a precise, electronic charge regulator to control battery terminal voltage during charging and an efficient wattage converter for stepping the voltage down to the required power supply output level. This unique feature allows the solar panels to operate at their peak power point for longer periods of time during the day. Printed circuit board LED indicators illustrate battery charging and converter functions.

Standard features include temperature compensation on the charge circuitry and load drop for lead acid battery protection during extended cold weather, or sunless periods. PC board is environmentally sealed: low loss FET's are used in battery charging and converter circuitry: Continuous potentiometer adjustment and solid-state circuitry are provided for fine current control. All functions are engraved into the instrument panel. Continuous reading voltmeter and ammeter are standard. Compression lugs are provided for battery, solar and load connections.
Reduced Energy at Night (REN) type is designed to provide 100% of the daytime current rating during daytime solar energy periods and a minimum of 1/2 the daytime current rating of the power supply at night. This approach works on well casings and coated pipelines where the structure maintains polarization and can be polarized during the daytime. Only a fraction of the current required to initially polarize a structure is needed to maintain polarization once the structure is polarized. The size and quantity of components required are reduced which results in lower total power supply costs.
Continuous Voltage Output (CVO) type is designed for use in areas where a constant voltage is needed to provide protection at the set level 24 hours a day. Once set, the output voltage stays at the set point and current output changes as the ground-bed resistance changes. A magnetic circuit breaker is provided for over current protection.

LVIP & NVIP solar power supplies provide constant voltage, current and potential control modes.

Constant Voltage Control mode: In this mode of operation, the power supply output voltage is adjusted up or down by the operator and is held constant at the set point. The rectifier's output current changes as load resistance changes.
onstant Current Control mode: When a constant current power supply is specified, the operator has the ability to adjust the output current to a maximum desired level. The power supply automatically adjusts its output voltage to maintain the desired current level as load resistance changes.
Constant Potential Control mode: The operator has the capability of setting the desired reference to structure potential. A permanent reference half-cell is required for the constant potential power supply to operate in this mode. The reference cell to structure potential is sensed by the controller and compared to set the potential programmed by the operator. If there is a difference between the two, the power supply automatically adjusts its output to compensate for the difference.
