Series resonance test equipment is the use of series resonant principle, the use of excitation transformer excited series resonant circuit, adjust the frequency converter output frequency, so that loop inductance L and sample C series resonance, resonant voltage is added to the sample voltage. The frequency conversion resonance test device is widely used in electric power, metallurgy, petroleum, chemical industry and other industries, and is suitable for the transfer and preventive testing of large-capacity, high-voltage capacitive test products.

BPXZ series resonant pressure device is mainly composed of variable frequency controller, excitation transformer, high voltage reactor, high voltage divider and so on. Variable frequency controllers are divided into two major categories, 20KW and above for the console type, below 20KW for the portable box type; it consists of controller and filter. The main function of the frequency conversion controller is to convert 380V or 200V sinusoidal alternating current of fixed amplitude and frequency into sine wave of adjustable amplitude and frequency. And provide power for the entire device. The role of the excitation transformer is to raise the output voltage of the variable frequency power supply to the appropriate test voltage. The high-voltage reactor L is an important part of the resonant circuit. When the power supply frequency is equal to 1/(2π√LCX), it is in series resonance with the test sample CX.

The frequency conversion series resonant test device is suitable for the AC withstand voltage test of 10KV, 35KV, 110KV, 220KV, 500KV polyhexene power cables. Suitable for 60KV, 220KV, 500KVGIS AC withstand voltage test. Applicable to large-scale transformers, generating sets frequency withstand voltage test; power transformer induction withstand voltage test; grounding resistance measurement.

Series resonance test equipment product name:

Series resonance, series resonance withstand voltage test equipment, frequency conversion resonance, frequency conversion series resonance, series resonance test equipment, series resonance principle, variable frequency series resonance device, series resonance device introduction This year, the company has always put "build a mass of people's satisfaction window" as a practice The entry point and focus point of the theme activity of “Two studies and one action” will be further detailed and measures to ensure good power supply and service. The first is to pay close attention to weather changes, and prepare emergency plans for bad weather in advance to ensure rapid assembly in bad weather, such as thunderstorms, to ensure prompt repairs and customer satisfaction. Second, to strictly regulate the marketing business process management and arrears recovery time, serious Read meter discipline, block various types of loopholes, formulate measures in detail, strengthen management, and standardize the daily behavior of employees; third is to open up a green channel, implement the first question, take charge of the time limit, and set up a report box in the business hall, where customers find The staff members are deliberately making things difficult, pushing and pulling, and dragging things up. They can report at any time and the marketing department will deal with them in a timely manner. Fourth, they require all window personnel to change their position, enhance service awareness and service consciousness, and all customer complaints are true and strict. Conduct accountability.

At the same time, Siping Chengjiao Company also disclosed work procedures and basic conditions of staff at business sites, implemented an effective complaints accountability system, further restricted employee behavior, and improved work efficiency and service quality. Since the beginning of this year, the company has always been “building a mass” As an entry point and focus point for the implementation of the theme of "Two studies and one action," the "window" will further refine the measures and do a good job in power supply and quality service. First, pay close attention to the weather changes, and prepare for bad weather emergency plans in advance. The series resonant test equipment can ensure rapid assembly in the severe weather such as thunderstorms and winds to ensure prompt repairs and customer satisfaction. Second, it strictly regulates the marketing business process management and owes fees and expenses. Electricity time, serious meter reading disciplines, plugging various loopholes, formulating measures from details, strengthening management, and standardizing employees' daily behaviors; third, opening up green channels, fulfilling the responsibility of the first question, completing deadlines, and setting up a report box in the business hall. , Where the customer finds that the staff members are deliberately making things difficult, pushing and pulling, and dragging things up, they can report at any time and the marketing department will deal with them in a timely manner. Fourth, all window personnel are required to empathize, enhance service awareness and service consciousness, where customer complaints are true. , All will be strictly responsible for accountability.

At the same time, Siping Chengjiao Company also disclosed the work flow and basic conditions of the staff at the business site, implemented an effective complaints accountability system, further restricted the work behavior of staff, and improved service efficiency and service quality. .
