1.Overview: Transformer oil acid tester is a fully automatic measuring instrument which adopts the extraction method to accurately detect the insulating oil acid value. This instrument can improve the working efficiency and test accuracy, and at the same time ensure the safety of the body by reducing the operator's contact with the samples and reagents. The acid value is the trace value of potassium sulfate that neutralizes the petroleum acid in 1g of oil, which contains a certain amount of inorganic acid and inorganic acid. The acid value includes organic and inorganic acids contained in the oil. In most cases, oil does not contain mineral acids. Therefore, the oleic acid value actually represents the content of organic acids in the oil. The organic acid contained in the new oil is mainly cyclonic acid. In the oil and in the process of use, the acid value of the oil produced by oxidation is an indicator to measure the degree of refining of the new oil. Whether the oil is running is an important indicator of the continued use of oil quality equipment. 2.

Product Introduction Capacitive voltage transformer (CVT) in calibration the test must be conducted under the condition of 50Hz frequency complex geographical condition on site at the same time the traditional experiment device is difficult to meet the requirements of on-site handling testing series resonance booster device is first used in domestic field tunable resonance device has been widely used in domestic 500 kv and below the field calibration of capacitor voltage transformer. Product Parameters Technical parameters Rated Capacity 80kVA rated voltage 160kV Adjustable inductance range 65~130H Rated frequency 50Hz Rated current 0.5A Adjustable gap range 0~300mm Product Characteristics 1 Due to full compensation of resonant reactive power the power of power supply and equipment is less than 1/10 of the required capacity of the subject (1/Q>10). Small size and light weight with the same capacity large output capacity of the device and small power capacity required cheap convenient and safe to use; 2 Series resonance is actually a current filtering circuit so that the current passing through the subject is basically the fundamental current and the waveform distortion rate (THD) of the output voltage is very small which is superior to all existing ac voltage withstand equipment. 3 The short circuit current of the sample after flashover or breakdown is only less than 1/10 (1/Q) of the test current before short circuit which can effectively prevent the expansion of damage to the fault point after breakdown; 4 After flashover the arc will be automatically extinguished immediately. The long (number of seconds) process of restoring resonant state voltage after arc quenching is a steady-state establishment process and there is no danger of voltage overshoot and no danger of restoring overvoltage in microsecond millisecond transient process.
