5 STP及互联网服务供应商的设计标准

5 STP and ISP design criteria

All electrical equipment will be rated for 45qC designed ambient temperature. The installation will generally conform to Indian Standards / IEC.

将所有电气设备额定45qC设计的环境温度。安装一般会符合印度标准/ IEC。



The following factors shall be considered for proper selection of electrical apparatus or equipment for areas where flammable gas or vapours may rise.

可燃性气体或蒸气可能上升为地方的电气设备或设备的正确选择应考虑以下因素。



a) Area classification a）地区分类

The classification of area shall be as per IS 5571 & IS 5572 , based on the degree of probability with which explosive concentrations of combustible gas or vapour may arise in installations in terms of both the frequency of occurrence and probable duration of existence on each occasion.

区域分类应为每IS5571和5572，爆炸性浓度的可燃气体或蒸气可能在安装发生的频率和每次存在时间可能出现的概率程度的基础上。



5.7 备用柴油发电机组 5.7 Standby diesel generator set

5.7.1 K&C Valley STP :

There shall be one no 11kV Standby Diesel Generator Set with AMF Panel & Acoustic

Enclosure. The capacity of the Standby Generator at shall be sized for power back up for all critical

loads which are required for continuous operation of the plant . The capacity shall be minimum of

50% of total working load of the Plant and 10% Contingency over these loads shall be considered

while sizing the DG Set.

须有一个没有11千伏备用柴油发电机与AMF面板及声学附件。备用发电机的容量应为权力大小，备份所有关键工厂连续运行所需的负载。容量应最低50％的总的工作负载，这些负载的厂房及10％的应急应被视为同时总干事集的大小。



Automatic Main Failure Panel :

One AMF (Automatic Main Failure Panel) shall be provided for each Diesel Generator Set. The AMF shall include two incoming circuit breakers, one from mains (BESCOM / KPTCL) and one from a standby power, with both electrical and mechanical interlock system between the mains and the standby power.

自动主要不合格小组：

应为每个柴油发电机组提供一个AMF（自动主要不合格小组）。 AMF的应包括两个传入的断路器，电源（BESCOM/ KPTCL），从一备用电源和电源之间的电气和机械联锁系统备用电源。



The capacitor banks provided shall be of bus connected type with Automatic Power factor correction, the system shall be designed such that a power factor of not less than 0.98 is maintained.

提供电容银行应自动功率因数校正，总线连接类型系统应设计，保持了不低于0.98的功率因数。



Automatically controlled multistage power factor correction shall be provided. 2 Nos. PFC panels providing no less than 8 No PFC stages per panel shall be provided each connected to one bus section of the distribution oard. The PF on each half of the board shall be monitored and corresponding PFC capacitors switched in and out automatically in discrete stages in order to maintain a set point PF value.

应提供自动控制多级功率因数校正。2号PFC板提供不低于8每块面板无PFC级应提供每个连接到一个配电板的总线部分。应监测和相应的PFC电容器切换和自动退出，以保持设定点PF值离散阶段。



Each panel shall be configured such that no PFC capacitor stages shall operate when the standby generator is powering the side of the distribution board to which it is connected. The breakers and cables in capacitor circuit shall be designed for taking extra loading of 35%.

每个小组应配置等，没有PFC电容阶段时，备用发电机供电的配电板，它是连接方。应设计为35％的额外负载电容电路断路器和电缆。
