The complete electrical equipment is a complete electrical equipment composed of shell, bus, primary and secondary elements, auxiliary materials, etc. Its operation in the power grid mainly plays the role of receiving and distributing electric energy, while playing the role of control and protection for electrical equipment. The electrical equipment is mainly divided into: 0.4KV, 0.69KV, 1.2kV low-voltage switchgear; 3.6kV, 7.2kV, 12kV, 24kV medium voltage switchgear, 40.5kV high voltage switchgear, power box (cabinet), lighting box (cabinet), protection screen, DC screen, etc.

电气设备产品型号主要有这三大类:

There are three main types of electrical equipment product models:

1、低压类：PGL（不推荐使用）、GGD（安全可靠且性价比高，因此被广泛使用）、BFC（不推荐使用）、GCL（K）（不推荐使用）、GBD、GCS（森源设计）、MNS （ABB公司）；

1. Low voltage category: PGL (not recommended), GGD (safe, reliable, and cost-effective, therefore widely used), BFC (not recommended), GCL (K) (not recommended), GBD, GCS (Senyuan Design), MNS (ABB Company);

2、中高压类：GG-1A（F）（现已淘汰，不推荐使用）、XGN2-12（不推荐使用）、KYN1-12（不推荐使用）、JYN2.6-12（不推荐使用）、HXGN-12（F）、XGN15-12（sf6）、KYN18-12、KYN28-12（目前市场主流产品）、KYN口-24（正在成为发展趋势）、JYN1-40.5（不推荐使用）、XGN口（JGN口）-40.5（不推荐使用）、KYN61-40.5（市场主流产品）、KYN96-40.5;

2. Medium and high voltage category: GG-1A (F) (now obsolete and not recommended), XGN2-12 (not recommended), KYN1-12 (not recommended), JYN2.6-12 (not recommended), HXGN-12 (F), XGN15-12 (sf6), KYN18-12, KYN28-12 (currently mainstream product in the market), KYN port-24 (becoming a development trend), JYN1-40.5 (not recommened), XGN port-40.5 (not recommended) KYN61-40.5 (mainstream products in the market), KYN96-40.5;

3、箱变类：YBM□-12（24、40.5）/0.4、ZGS9（11）-12（40.5）/0.4、10KV中压开关站、35KV高压开关站。

3. Box type transformer: YBM □ -12 (24, 40.5)/0.4, ZGS9 (11) -12 (40.5)/0.4, 10KV medium voltage switchgear, 35KV high voltage switchgear.

作为一个电器成套设备的报价员必须能够看懂并理解一次系统图、二次原理图、平面布置图，及三者之间的相互关系。这需要报价员平时多看多学多问。

As a quotation person for complete electrical equipment, one must be able to understand and understand the primary system diagram, secondary schematic diagram, layout plan, and the interrelationships among the three. This requires the quotation staff to read, learn, and ask more frequently.

在电器成套设备中把母线、隔离开关（高压）、刀开关（低压）、断路器（空气开关）、电压互感器、电流互感器、电力变压器、交流接触器、保护继电器（热继电器）、避雷器等组成的设备叫一次设备。由它们按照原理关系所组成的回路称为一次回路或一次方案图。为了使一次系统能安全可靠、稳定地运行，随时监视一次系统运行状态，同时能随时控制一次系统所必须配备许多其他电器元件及设备，如：测量仪表（电流表、电压表、功率因素表、功率表、频率表等）、控制信号元件（信号灯、按钮、万能转换开关等）、继电保护装置等。由它们按照原理关系所组成的回路称为二次回路或二次方案图。

In the complete set of electrical equipment, the equipment consisting of bus, disconnector (HV), knife switch (LV), circuit breaker (air switch), Voltage transformer, current transformer, power transformer, AC contactor, Protective relay (thermal relay), lightning arrester, etc. is called primary equipment. The circuit composed of them according to their principle relationship is called a primary circuit or a primary scheme diagram. In order to ensure the safe, reliable and stable operation of the primary system, monitor the operation status of the primary system at any time, and control the primary system at any time, many other electrical components and equipment must be equipped, such as: measuring instruments (Ammeter, Voltmeter, power factor meter, power meter, frequency meter, etc.), control signal elements (signal lamps, buttons, universal change-over switches, etc.), relay protection devices, etc. The circuit composed of them according to their principle relationship is called a secondary circuit or a secondary scheme diagram.
