Description
Description

1、 Overview PW‐12/24/36,is suitable for the rated voltage 12/24/36 kV,rated current 630A 50/60Hz power     grid open circuit,load current in closed Power system overload current. This load switch can separate those broken distribution line automatically.  With the latest techno logy, it has the newest electronic controller.The switch can be used by manual operation, electric operation and operation from a long distance. Electronic controller is   installed in a stainless   steel cabinet which is suitable for using under all kinds of climatic conditions. In addition, there   are some wired and wireless modem installed in the cabinet through which it can realize the   remote monitoring and control. Simple installation on column is convenient, fast, and also can re duce the construction cost.

2、The standard conditions of use      operating conditions for SF6 gas load switch to adapt to: 2.1  Ambient temperature 2.1.1 Ambient air temperature: upper limit +50 ° C, lower limit of ‐40 ℃. 2.2 Elevation does not exceed 1000m;2000m;3000m; 2.3 The pressure does not exceed 700pa (equivalent to wind speed of 34m / s) 2.4 Earthquake intensity: 8 degrees 2.5 Pollution class: class III, class IV.

3 Features 3.1 SF6 gas‐insulated 3.2   Drive pipe with large diversity 3.3   Visible open / closed status 3.4 Quick operation 3.4.1 operating mechanism with spring energy to ensure a quick closing and opening operation.   3.5 Can realize remote control 3.5.1 It is equipped with electronic controller, fit for in situ operation as well as FTU interface   console operation. 3.6 Rugged switch 3.6.1 The switch is made of proven durable, corrosion‐resistant materials (special used in   warships 304L stainless steel plate)which ensures that there is a very long service life (30 years),   and can be implement a series of operations.It has the ideal characteristics as a column   equipment. 3.7 Standard 3.7.1 Each switch before leaving the factory has been filled with SF6 gas, sealed, and test accordin g to IEC60265‐1 (1988), GB3804‐1990 standard.
