■ Product overview

VS-2921 Insulating rod horizontal withstand voltage test platform is mainly used for the overall power frequency withstand voltage test of insulation tools such as 500kV and below insulation rods. The test system is controlled by the main control test bench, without partial discharge test transformers, voltage dividers, and metal protection Boost equipment such as resistance, and horizontal lifting high-voltage test platform. The insulating rod lifting and voltage-resistant platform adopts a horizontal structure, and the two ends are pressurized, and the opposite polarity test voltage is applied at both ends to form a voltage doubling effect. The voltage to ground at both ends is 50% of the rated test voltage, which greatly reduces the value of the voltage to ground and greatly reduces the height of the test platform. The clearance height of the test site is greater than 6.5 meters to meet the insulation requirements. Electrode trolleys are installed on both sides of the insulating rod voltage-resistant platform, which can move up and down to facilitate the placement of test samples. The insulating rod is hoisted horizontally for voltage resistance test.

■ Features

▲ The rated voltage of the withstand supports on both sides of the horizontal withstand voltage platform is 300kV, and the reverse polarity voltage double mode is used to boost the voltage. The withstand voltage test voltage reaches 600kV, and the entire insulation rod withstand voltage test of 500kV and below can be carried out.

▲ The total height of the horizontal pressure-resistant platform is 3.4 meters, with a pressure equalizing cover on the top to reduce partial discharge.

▲ The horizontal pressure-resistant platform has a lifting trolley that rotates synchronously through an insulated rod screw, which can move up and down, which is convenient for loading and unloading test products.

▲ Two sets of brackets, one end is fixed, the other end can be moved along the track electrically to adjust the pressure resistance length.

▲ The pressure resistance platform uses laser to measure the pressure resistance distance, and the pressure resistance length is displayed digitally.

▲ There are 24 stations on the lifting trolley, which can hang 24 insulating rods at a time.

▲ The insulating rod adopts stainless steel special test fixture, which is tightly embraced to meet the standard requirements, and is easy to install and unload.

▲ A laser distance measuring device is installed on the base, which can digitally display the test length of the insulating rod.
