柜我們又常稱其為母線電壓互感器柜或電壓互感器柜。里面一般設置有電壓互感器一套、熔斷器一、避雷器等主要電器原件。熔斷器的保險絲為電壓互感器提供保護。電壓互感器是將高壓按一定的變比將高壓按比例轉換成低壓的裝置，使其適應儀表的電壓要求。
Cabinet, also known as busbar voltage transformer cabinet or voltage transformer cabinet. There is usually a set of voltage transformers, a fuse, a lightning arrester, and other main electrical components installed inside. The fuse of the fuse provides protection for the voltage transformer. Voltage transformer is a device that converts high voltage into low voltage proportionally according to a certain transformation ratio, making it suitable for the voltage requirements of the instrument.
避雷器主要起到過電壓和防雷保護。
The lightning arrester mainly serves as overvoltage and lightning protection.
電壓互感器柜一般情況下采用組合式的結構，我們可根據工程的具體設計參數，配置不同類型和數量的PT。
The voltage transformer cabinet generally adopts a combined structure, and we can configure different types and quantities of PT according to the specific design parameters of the project.
柜的整體結構采用可拆卸金屬鎧裝結構，設備面板上通常設有大面積的觀察口。它可以隨時觀察PT柜的運行情況。每臺PT設有一節車廂，其一、二次回路采用分接結構，實現一、二次室分離。柜體整體美觀可靠，可實現現場抽取維護。
The overall structure of the cabinet adopts a detachable metal armor structure, and the equipment panel usually has a large area of observation ports. It can observe the operation of the PT cabinet at any time. Each PT is equipped with a carriage, and its primary and secondary circuits adopt a tap structure to achieve separation of the primary and secondary compartments. The overall appearance and reliability of the cabinet can achieve on-site extraction and maintenance.
PT柜的功能
Function of PT cabinet
（1）提供電氣系統中的測量電壓、儀器儀表電壓和保護電壓。
(1) Provide measurement voltage, instrument voltage, and protection voltage in the electrical system.
（2）為功率表提供測量電壓。
(2) Provide measurement voltage for the power meter.
（3）可為相關設備提供操作和控制電源（PT）。
(3) It can provide operation and control power (PT) for relevant equipment.
（4）滿足電氣系統繼電保護的需要。母線絕緣、欠電壓、過電壓、備用設備自投條件等。高壓柜屏頂電壓小母線由PT柜供電。
(4) Meet the needs of electrical system relay protection. Bus insulation, undervoltage, overvoltage, backup equipment self switching conditions, etc. The voltage small busbar on the top of the high-voltage cabinet screen is powered by the PT cabinet.
柜內有測量PT和計量PT（原來要求是要分開測量PT和計量PT，如沒有特殊要求也可以不分開，可以共用）。頂部的小母線可用于向其他高壓柜提供電源。同時為其它設備提供電源，滿足測量、計量和保護電源的電壓要求。
There are measuring PT and measuring PT in the cabinet (the original requirement was to separate the measuring PT and measuring PT, but if there are no special requirements, they can be left separate and can be shared). The small busbar at the top can be used to provide power to other high-voltage cabinets. Simultaneously providing power supply for other equipment to meet the voltage requirements for measurement, metering, and protection power supply.
PT柜和計量柜的區別
The difference between PT cabinet and metering cabinet
柜是電壓互感器柜（PT為電壓互感器的英文縮寫），通常用于裝設接于母線上的電壓互感器，此電壓互感器可用于測量和保護。
Cabinet is a voltage transformer cabinet (PT stands for voltage transformer), usually used to install voltage transformers connected to the busbar. This voltage transformer can be used for measurement and protection.
電力部門為了準確計量并能對各用戶進行有效的計量管理，在用戶側會設一個專用的計量柜，柜內配置電壓互感器、電流互感器及計量儀表。此表計的數據用于電費的結算。計量柜的管理權限為電力部門，用戶無權進行維修和調試等工作。
In order to accurately measure and effectively manage various users, the power department will set up a dedicated measuring cabinet on the user side, which is equipped with voltage transformers, current transformers, and measuring instruments. The data in this table is used for the settlement of electricity bills. The management authority of the measuring cabinet is the power department, and users have no right to carry out maintenance and debugging work.
