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(shè)備產(chǎn)品型號(hào)主要有這三大類(lèi):

There are three main types of electrical equipment product models:

1、低壓類(lèi)：PGL（不使用）、GGD（可靠且性?xún)r(jià)比高，因此被廣泛使用）、BFC（不使用）、GCL（K）（不使用）、GBD、GCS（森源設(shè)計(jì)）、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(lèi)：GG-1A（F）（現(xiàn)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(chǎng)主流產(chǎn)品）、KYN口-24（正在成為發(fā)展趨勢(shì)）、JYN1-40.5（不使用）、XGN口（JGN口）-40.5（不使用）、KYN61-40.5（市場(chǎng)主流產(chǎn)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(lèi)：YBM□-12（24、40.5）/0.4、ZGS9（11）-12（40.5）/0.4、10KV中壓開(kāi)關(guān)站、35KV高壓開(kāi)關(guān)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(gè)電器成套設(shè)備的報(bào)價(jià)員必須能夠看懂并理解一次系統(tǒng)圖、二次原理圖、平面布置圖，及三者之間的相互關(guān)系。這需要報(bào)價(jià)員平時(shí)多看多學(xué)多問(wèn)。

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(shè)備中把母線(xiàn)、隔離開(kāi)關(guān)（高壓）、刀開(kāi)關(guān)（低壓）、斷路器（空氣開(kāi)關(guān)）、電壓互感器、電流互感器、電力變壓器、交流接觸器、保護(hù)繼電器（熱繼電器）、避雷器等組成的設(shè)備叫一次設(shè)備。由它們按照原理關(guān)系所組成的回路稱(chēng)為一次回路或一次方案圖。為了使一次系統(tǒng)能可靠、穩(wěn)定地運(yùn)行，隨時(shí)監(jiān)視一次系統(tǒng)運(yùn)行狀態(tài)，同時(shí)能隨時(shí)控制一次系統(tǒng)所必須配備許多其他電器元件及設(shè)備，如：測(cè)量?jī)x表（電流表、電壓表、功率因素表、功率表、頻率表等）、控制信號(hào)元件（信號(hào)燈、按鈕、轉(zhuǎn)換開(kāi)關(guān)等）、繼電保護(hù)裝置等。由它們按照原理關(guān)系所組成的回路稱(chēng)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.
