Wuhan Wei Austrian three high Electrical Equipment Co., Ltd. - WAYM salt density meter Product Description: WAYM direct reading salt density instrument developed for power system anti flashover detection, used to measure the surface of the insulator equivalents with salt density (hereinafter referred to as "salt dense"), a special measuring instrument, but also can measure the conductivity of the solution and temperature. Machine in its measurement of high precision, intuitive readings, measuring range, easy-to-use features widely used in electricity, teaching, research, and other related industries. Pollution class division and draw maps of pollution class is the basis of the work of the anti flashover, accurate maps of pollution class select input, substation equipment electrical porcelain insulation creepage distance basis. Insulator surface contour attached salt density values ??determine electrical porcelain insulation the severity quantitative data of the filthy condition, is one of the important basis for the division of the pollution class and draw the diagram of the polluted area. The salt density measurements Therefore, of great significance to the safe operation of the power system. Reference standard: GB/T16434 - 1996 "choose and the size of the high-voltage insulator in high voltage overhead lines and power plants, substations the environment filthy grading and external insulation selection criteria" GB/T16434-200X "filthy conditions determine Part 1: Define information and the general principles of the State Grid Corporation of Q/GDW152-2006 "high voltage overhead lines and power plants, substations environment polluted area classification and external insulation selection criteria" features: a) with automatic range switching function. b) measuring range, the the salt density range 0.0001mg/cm2 to 9.9999mg/cm2. c) automatic temperature compensation, directly at 20 ° C when the standard conductivity and equivalents the attached salt density (ESDD). d) using a conductivity greater than cleaning liquid of 10μs/cm, having automatically eliminate the function of the cleaning liquid conductivity and the original salt content. Reducing the requirements of the cleaning liquid. e) by the Charged correction factor, automatically uncharged measuring salt density (ESDD) was converted to a live line measurement of salt density (ESDD). f) storage / print / data upload function, can store 400 groups of data. g) built-in high-capacity rechargeable lithium battery, suitable for field use. Product parameters: 1. Measuring range: salt density: 0.0001mg/cm2 9.9999mg/cm2 (X-4.5 insulator prevail) measure temperature: 0 ° C to 100 ° C measuring conductivity: the 0 ~ 100000μs/cm 2.
