China's power regulations stipulate that when 10kV and 35kV system capacitance currents are greater than 30A and 10A, respectively, arc suppression coils should be installed to compensate for capacitive currents. This requires that the capacitance of the distribution network be measured to determine.
In addition, the PT ferro-resonant overvoltage is generated by the capacitance of the distribution network and the parameters of the PT. In order to verify whether the PT resonance occurs in the power distribution system and what kind of resonance occurs, the distribution network must also be accurately measured. Ground capacitance.
Methods to measure the capacitance of the distribution network include direct method of single-phase metal grounding, indirect measurement of additional capacitance, and addition of signals in PT open triangles. However, the most popular and frequently used ones in the field are neutral capacitors. law.
Automatic capacitance current tester uses neutral point capacitance method to measure distribution network capacitance current. The tester adopts large-screen liquid crystal display and Chinese menu. After the safety measures are taken, the instrument parameters need not be touched after setting the instrument parameters in advance. Make this work safe, simple and fast, and the test results are accurate, stable and reliable, and are not affected by other operating conditions, especially when the system is not balanced.

The Single Girder Gantry Crane is mainly used outdoor working site for hoisting and moving of materials. It has the advantages of simple structure, convenient transportation and installation, light self-weight, and the main girder is mostly a derailed box-shaped frame structure. Single girder Gantry Crane is usually used for lifting weight ≤ 50 t and the span ≤ 35 m. 


Single Girder Gantry Crane L


Single girder gantry crane legs can be L- and C-type. The L-type single girder gantry crane is easy to install, stable structure, light slef-weight. However, the space for lifting cargo through the legs is relatively small. The C-shaped legs are made of a slanted or curved shape with the purpose of having a large lateral space for the goods to pass through the legs.


Single Girder Gantry Crane Weihua


Weihua also provide European standard (FEM and DIN standard) single girder gantry crane which has the advantages of compact structure design, light self-weight, smooth running, world class brands components and electrics, less noise, less consumption, large working space, precise positioning, etc. The Electric Hoist is also FEM and DIN standard.
