41. 相关知识：
42. 负荷开关特点：
43. A、可以隔离电源，有明显的断开点，多用于固定式高压设备。 　　
44. B、具有灭弧装置和一定的分合闸速度，在合闸状态下可以通过正常工作电流和规定的短路电路。 　　
45. C、严禁带负荷接通和断开电路，常与高压熔断器串连使用。（功能接近于高压断路器，可以简化配电装置及继电保护，降低设备费用）
46. 高压负荷开关是一种功能介于高压断路器和高压隔离开关之间的电器，高压负荷开关常与高压熔断器串联配合使用；用于控制电力变压器。高压负荷开关具有简单的灭弧装置，因为能通断一定的负荷电流和过负荷电流。但是它不能断开短路电流，所以它一般与高压熔断器串联使用，借助熔断器来进行短路保护。

[Supply] FN5-10R/630 HV load switch fn5-12r/400a load switch factory
FN5-10R/630 price, FN5-10R/630 manufacturers, FN5-10R/630 professional manufacturer
We are a professional manufacturer, such a load switch now only used for maintenance. So often available spot to prepare urgently needed! ! !




The product FN5-10R/400 and FN5-10R/630 difference:
FN5-10R/400 on behalf of the rated current 400A load switch.
FN5-10R/630 on behalf of the rated current 630A load switch.
No other difference between the two parameters. The voltage Similarly 10KV. The price is the same. Please inquire ...




FN5-10R/630 HV load switch details are as follows: ↓ ↓
This product belongs to one of the high-pressure phase out the product, but the market demand. Because the previously purchased FN5-12R/630A life to need to be replaced.
Product Selection: R representative with fuse bases, fuse to play a protective role in the line!
Products without the fuse work can, without the advantage of cost savings.

FN5-10R-type indoor AC HV load switch-fuse combinations I plant absorbing foreign advanced technology, combined with China's power supply requirements, designed and developed by the




Fully-test and a long-term trial run assessment, performance reached IE20 "3-63KV AC high voltage load switch standard requirements, compared with similar foreign products, technical parameters




Reached the level of similar products with small size, light weight, and can be used for RMU and box-type substation, widely used in 12KV power distribution line, and avoid equipment




The missing running.
Successfully developed the product to fill to fill the domestic blank, three-position switch, isolation and grounding.




Working conditions
1, an altitude of over 1000 meters;
2, the ambient air temperature: no higher than +40 ℃ and not less than -25 ° C;
3, air relative humidity: daily average of not more than 95%, the monthly average of not more than 90% (+25 ° C);
4, the ambient air should not corrosive, flammable gas and other obvious pollution;
5, no regular strenuous exercise.

Load switch features:
A, can be isolated from the power supply, there is a significant disconnect point used for stationary high-voltage equipment.
B, with the arc extinguishing device, and a certain sub-closing speed, in the closed state by the normal operating current and a predetermined short circuit.
C, non-band load switching on and off the circuit, often associated with high-voltage fuse in series. (Close to high voltage circuit breaker can be simplified distribution equipment and relay protection, reduce the cost of equipment)
HV load switch is a function of the range appliances, high voltage load switch often between the high voltage circuit breakers and high-voltage isolation switch in series with the use of high-voltage fuse; used to control power transformers. Simple interrupter device, high voltage load switch-off some of the load current and load current. But it does not disconnect the short circuit current, so it is generally used in tandem with the high-voltage fuse, with the fuse for short circuit protection.
