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.

電氣設備產品型號主要有這三大類:

There are three main types of electrical equipment product models:

1、低壓類：PGL（不使用）、GGD（可靠且性價比高，因此被廣泛使用）、BFC（不使用）、GCL（K）（不使用）、GBD、GCS（森源設計）、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、中高壓類：GG-1A（F）（現已淘汰，不使用）、XGN2-12（不使用）、KYN1-12（不使用）、JYN2.6-12（不使用）、HXGN-12（F）、XGN15-12（sf6）、KYN18-12、KYN28-12（目前市場主流產品）、KYN口-24（正在成為發展趨勢）、JYN1-40.5（不使用）、XGN口（JGN口）-40.5（不使用）、KYN61-40.5（市場主流產品）、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、箱變類：YBM□-12（24、40.5）/0.4、ZGS9（11）-12（40.5）/0.4、10KV中壓開關站、35KV高壓開關站。

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.

作為一個電器成套設備的報價員必須能夠看懂并理解一次系統圖、二次原理圖、平面布置圖，及三者之間的相互關系。這需要報價員平時多看多學多問。

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.

在電器成套設備中把母線、隔離開關（高壓）、刀開關（低壓）、斷路器（空氣開關）、電壓互感器、電流互感器、電力變壓器、交流接觸器、保護繼電器（熱繼電器）、避雷器等組成的設備叫一次設備。由它們按照原理關系所組成的回路稱為一次回路或一次方案圖。為了使一次系統能可靠、穩定地運行，隨時監視一次系統運行狀態，同時能隨時控制一次系統所必須配備許多其他電器元件及設備，如：測量儀表（電流表、電壓表、功率因素表、功率表、頻率表等）、控制信號元件（信號燈、按鈕、轉換開關等）、繼電保護裝置等。由它們按照原理關系所組成的回路稱為二次回路或二次方案圖。

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.
