Specializing in the production of high-precision KJTC-IV high-voltage switch characteristics tester - Shanghai 100 KJTC-IV high-voltage switch mechanical characteristics tester, is a newly designed special instrument to detect the mechanical dynamic characteristics of high-voltage circuit breakers. The instrument uses high-tech technology, set computer, printer, measurement interface circuit, operating power is one, is a new special instrument for high-voltage circuit breaker detection. The test instrument is equipped with two kinds of displacement sensors that are suitable for different distances and accuracy tests. The automatic identification system of the instrument identifies the selected sensors and completes the measurement of less oil, more oil, sulfur hexafluoride, and vacuum high voltage circuit breakers. Distance, speed. In the design of the instrument, only one action (separation) is required, that is, all the data samples of the six fractures can be recorded, the measurement results can be displayed with a single key operation, and the measurement data can be printed, and the current waveform of the six fractures can be printed. Figure and a fractured moving contact time characteristic curve. The instrument is designed in strict accordance with the definition of the national standard "GB 1984" and "GB 3309" for data processing.
Specializing in the production of high-precision KJTC-IV high-voltage switch tester features and features:
1, test function
(1) Simultaneously measure one to six fractures in sequence
(2) Simultaneously measure one to six fractures in different phases of three phases
(3) Simultaneously measure one to six fractures in different phases of the same phase
(4) Simultaneous (partial) gate time measuring one to six fracture ms at the same time
(5) Simultaneous (central) brake bounce time is measured simultaneously with one to six fracture ms
(6) Speed ​​(tower) brake speed measurement one fracture m/s
(7) Measuring the maximum speed of the brake (m)
(8) Measure the average speed of the brake (m)
(9) Measure one to six fractures mm at the same time
(10) Moving contact overtravel (contact stroke) Simultaneously measuring one to six fractures mm
(11) Convergence time (Metal short time) ms
(12) No flow time (automatic reclosing no current interval) ms
2, the main performance and features of the instrument
(1) The instrument uses a high stability device. Floating, large-area, digital filtering and other anti-jamming technologies.
(2) The instrument is equipped with two types of displacement sensors, which are suitable for detecting high-voltage circuit breakers with different distances, speeds, and precision requirements. After different sensors are inserted, the instrument will automatically recognize them. The instrument can automatically recognize the operation of the high voltage circuit breaker (separation) gate and the reclosing operation, and automatically collect all kinds of data after the operation. The measurement calculation process is done automatically by the CPU.
(3) The instrument has automatic identification ability and strong self-protection function for the wiring error of the high-voltage circuit breaker during measurement and the wrong instruction and unsuccessful operation.
(4) The instrument's sequence of coincident (sub-) gates and the actual closing time of each fracture shall be displayed. It provides the basis for repairing and debugging the three phases of the high-voltage circuit breaker in different phases and different phases of the same phase. The data is automatically displayed with 0.1 milliseconds of data.
(5) The instrument measures the stroke and overtravel of the moving contact. As long as the sensor is installed on the fracture of any phase of the high voltage circuit breaker, the trip and overtravel data of each three-phase fracture can be measured and calculated at the same time. The measurement accuracy is 1% second meters.
(6) The power box provides 0 to 250V DC operating power to directly operate the high voltage circuit breaker. Applicable to electromagnetic control, hydraulic, spring energy storage and other DC control operating mechanism.
(7) The instrument is small in size, light in weight, simple in operation, and easy to carry. It is especially suitable for field flow detection and on-site maintenance testing of substations. It is an indispensable tool for high-voltage circuit breakers in production, inspection, maintenance and debugging.
Polyurethane filtration material
Describe:
The filter net cotton is a net structure which is made of polyurethane filter foam cotton by opening the membrane to open the membrane. The filter net cotton has a high porosity of more than 97% and a opening rate up to 99%. It has good air permeability and high mechanical strength. Therefore, the filtration material has the characteristics of low flow resistance and high filtration efficiency. And can be washed repeatedly, showing durable, economic, environmental protection and other advantages.
Characteristics:
The polyurethane filter medium is made from the common porous soft foam through the netting treatment, which removes the original face or wall film between the foam network, and obtains the main skeleton network structure. The porosity of the filter sponge is as high as 97%, with excellent permeability, good softness and high mechanical strength.The black filter Sponge has the characteristics of full opening, strong tension, high sound absorption and good permeability.
Application:
It is used for motorcycle, automobile filter, filter equipment, aquarium, gas mask, air conditioner, high permeability cushion, mattress, activated carbon filter substrate, ceramic filter substrate and so on. And oil-resistant polyester filter. Slow rebound filter, etc.
