油浸式負荷開關（二工位35kV）

本開關應用于組合式變壓器，負荷開關有四位置和二位置開關，四位置開關按結構形式不同可分為丁型、V型和}型。開關安裝在組合變壓器的箱壁上，以變壓器油為絕緣和滅弧介質，適用于頻率50日z，設備最高電壓12kV, 40.5kV，額定電流315A, 630A三相供電線路，在終端供電或環(huán)網供電系統(tǒng)中，作為工業(yè)、民用電能的控制和保護裝置。在操縱桿的作用下，能使開關在組合式變壓器帶負荷狀態(tài)下，作三相聯(lián)動關、合電源或改變供電方式。

Specification

BFY型油浸式負荷開關
BFY type oil-immersed load break switch

This switch is used for compounded type transformer. It is classified into four-position and two-position products. Thefour-position switch is divided into“T”type、“V”type and“I”.The switch is installed on the tank well of compoundedtransformer, the transformer oil is used for its insulating and are eliminated material. It is suitable for three phase power supply circuit with rated frequency 50Hz, highest voltage for equipment 1 2kV、40.5kV, rated current 315 A and 630A. In the radialfeed or loop feed supply system, it is used as controlling and protective device in the industry civil used electric energy. When functioned by operating pole, the switch can drive three phase linkage cut and close power resource or transfer supply method.

如需35kV兩工位負荷開關獨立接線兩開兩閉型號為BFY3I2-35/630-20- II K2
If 35kV two-position load switch with independent wiring is needed The type of BFY312-35/630-20- II K2 has two open and two close working position.

開關外形安裝尺寸圖(電動操作在開關型號后加D).如35kV兩工位電動操作型號為BFY312-35/630-20-D:
Outline installation drawing for load switch《For electric -driven operation type with the letter D》,BFY312-35/630-20- II -D is of 35kV electric -driven operation type.

兩工位負荷開關帶電動操作機構FD-1型，其結構緊湊可靠。安裝簡單方便，具有明顯的分合狀態(tài)指示。與控制器配合既可電動操作，又可直接手動操作.操作轉換靈活、方便。
Two-position load switch with electric-driven operating mechanism is called type FD-1 .The product is compact and reliable, and easy to install, the open and close statue is marked very clearly，it is suitable for automatic and manual operation， the control mechanism could be converted flexibly and conveniently.

1.控制器工作電壓:AC 220V;
2.電動操作機構的控制器必須始終保持有電源，電源不能從變壓器低壓側直接接出，要有另外的備用電源，這樣才能保證負荷開關在切換過程中不因變壓器斷電而使電動機構的電機突然停轉，防止機構不到位而卡死;
3.控制器電纜線配長5m，如需加長請用戶提出。

1.Controller operating voltage:AC 220V;
2.The controller with power-driven operating mechanism must always maintain a power supply, the power supply can not be directly connect to the low-voltage side of the transformer, there must be an additional backup power, so as to ensure that the motor in the power-driven mechanism will not suddenly stall due to the power outage of transformer while the load switch is switching, preventing mechanism is not in place and stuck;
3. Controller cable shall be 5 meter long, if need longer please putting forward by users.
