DC Hipot Tester, High Voltage Direct Current Generator for Power Cable and Arrester Test

GDF DC Hipot Tester,High Voltage Direct Current Generator for Power Cable and Arrester Test

Introduction:

• GDF Series DC Hipot Tester,High Voltage Direct Current Generator is an important equipment for DC voltage withstand test and leakage current test of HV electrical equipment, cables, surge arresters in electriv industry and power supply departments;

• GDF Series DC Hipot Tester,High Voltage Direct Current Generator is developed based on the calibration made by National HV Meterage Station, it accords with the standard "Generation Requirement of Portable DC HV Generator"(GDF 24003-90);

• The new technology, new material and optimal selected components are applied, It has the advantages of high power, small volume, light weight, good performance and high stability;

Specifications:

• Power: AC220V+10%, 50Hz+1%;

• Output voltage indicator accuracy:<1%;

• Output current indicator accuracy:<1%;

• Ripple contain factor:<0.5%;

• 0.75 times output voltage indicator accuracy:<1%, can be locked;
   

Model Selection:

Features:

• High reliability: high frequency voltage multi-doubler rectifier, simple circuit, high overload capability, rare fault, without maintenance.

• Small volume: one person can carry the largest DC HV generator (200kV/2mA). Its volume is only 1/(2~5) as the volume of the same kind of equipment made in Japan. It reaches the advanced level in the world.

• Perfect seal by metal housing, high mechanical strength. Its performance will not be influenced by vibration, moisture, dust and meteorological condition.

• Safe, convenience in operation, metal housing grounded. built-in HV terminals.

• There is no high voltage and low voltage connect outside, easy connection.

• Good auto protection function. It can nor be switched on if the HV output knob is not at zero position. Operation is simply. It automatically switch off in over voltage and over current case. There is dam pong resistor inside.It is not necessary to connect damping resistor outside.

• Excellent accuracy: The leakage current at HV side is measured by digital meter accuracy: 1uA, range switch is not required, discharge withstand current measurement function is available at low voltage side, It use precise resistor with good stability to measure high voltage.

Biomass Burner

The biomass burning machine needs to work under negative pressure. At the same time, the ID fan must be installed to ensure the negative pressure. If it is applied to aluminum melting furnace, greenhouse heating, drying room and other working conditions, it can be operated at slightly positive pressure. However, it is necessary to ensure the smooth flow of the flue; the cross-sectional area of the exhaust outlet and the power of the induced draft fan will be carried out according to the requirements specified by the engineering department of our company.

It must be equipped with a special operator to operate, the operator must be guided by the machine can operate the machine. If the product is used in a boiler, it should be submitted to a qualified boiler installation company for installation. If there is a size deviation due to the size of the burner mouthpiece, the size of the boiler's crater must be corrected. The product must be reported to the local boiler inspection office for approval. Qualified boiler maintenance unit.
