Leakage protector tester should pay attention to what issues
Overview: The installation of residual current protection device is an important technical measure for electricity safety. The relevant national standards and technical regulations make clear requirements and strict regulations for its operation and management. GB13955 "Installation and Operation of Residual Current Operation Protection Device" The management of missing-in-service operation specifically requires the test of the operating characteristics (leakage action current and segmentation time). In actual operation, the existing detection equipment has complicated operation, poor safety, unstable performance, high failure rate, and is not portable. Factors such as the development of daily management work.

After extensive investigations and hearing suggestions from many parties, we successfully developed the SHY Series Leakage Protector Detector. Our self-designed, researched and developed SHY Smart Pocket Digital Leakage Current Protector Tester Series is a special testing instrument for detecting various types of residual current operation and protector operation performance (leakage action current, leakage action breaking time). Product standards with reference to GB6829-95 and other related standards. Beijing Tongde Venture Professional Casting Quality
The current SHY-6000C Leakage Current Protector Tester is a relatively advanced large current, large capacity, small size, multi-function, high accuracy, liquid crystal display, reading retention, automatic detection, easy operation, one-click completion, easy to carry It is widely used in electric power companies, agricultural power security inspections, and general electricians. It is also used in labor security inspection departments such as leakage insurance manufacturers, construction, petroleum, railways, and so on. Beijing Tongde Venture Professional Casting Quality

There are five general body styles of Ball Valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve-especially the casing that contains the ball itself-are manufactured and assembled. The valve operation is the same in each case.
In addition, there are different styles related to the bore of the ball mechanism itself.
Ball Valves in sizes up to 2 inch generally come in single piece, two or three piece designs. One piece ball valves are almost always reduced bore, are relatively inexpensive and generally are throw-away. Two piece ball valves are generally slightly reduced (or standard) bore, they can be either throw-away or repairable. The 3 piece design allows for the center part of the valve containing the ball, stem & seats to be easily removed from the pipeline. This facilitates efficient cleaning of deposited sediments, replacement of seats and gland packings, polishing out of small scratches on the ball, all this without removing the pipes from the valve body. The design concept of a three piece valve is for it to be repairable.
