Overview discharge rods, also known as: Flexible high-pressure discharge rods, high-voltage discharge rods. High-voltage discharge rod using the new insulation material processing. It has lengthen, but also shrink characteristics. Portable telescopic high-voltage discharge rod for ease of use in various outdoor high-voltage test, especially after doing the DC voltage test, the charge accumulated on the sample, were discharged to ground, to ensure personal safety. Telescopic high-voltage discharge rod portable, convenient, flexible, small size, light weight, safe. 2 The main technical parameters Edit 1, discharge rods shrink dimensions: length 220mm, an outer diameter of φ25. 2, the discharge rods shrink the number of sections: 5. 3, the discharge rods stretch Size: stretching the length of 850mm. 4, the discharge voltage range: 5kV ~ 70kV. Use 1, a portable retractable telescopic part high-voltage discharge rod all the way out. 2, the internal preparation of a good grounding cord into a discharge head end portion of the rod jack and the other end of the ground connection to the earth, the ground to be reliable. 3, the discharge should be in the test is completed, the step-up DC generator control knob to the zero position on the box, then you can observe the DC high voltage generator control box on the voltmeter drops to about 15kV ~ 20kV, before discharge. 4, first with the tip of the discharge should be pointed metal discharge rods, slowly go near the power has been disconnected test sample. At this discharge rods release energy through a discharge resistor is discharged to ground. Then use the hook on the discharge line to the grounding rod hook test, a second direct-to-ground discharge. Caution 1, large capacitance discharge test, shall, after completion of the test, disconnect the test power should wait for some time, the charge on the sample by sample times the pressure tube and the ground itself self-discharge. Then you can observe the control voltage digital voltmeter box on the gradual decline in fall, when the voltmeter voltage drops to a lower voltage, usually around 5kV ~ 15kV, only to gradually move to stick with the discharge near the test. Free discharge of air through the gap first, then you can hear a hissing sound, when there is no sound when using the rod tip to touch sample discharging, and finally the test directly to ground discharge. 2, the sample size is large capacitive charge buildup size and sample capacitors and the applied voltage level proportional to the length of time. 3, after a few kilometers of high-voltage cables above the end of the test, the discharge time generally have very long, and the need to repeatedly discharge. Resistance capacity to large, need to order large-capacity discharge rods. 4, prohibited the discharge did not pull the stick to test the power supply test to discharge. 5. Do not use heavy compression foot and discharge rods, non-bent, broken, discharge rods. 6, prohibited the discharge rods moisture, affect the insulation strength should be stored in a dry place. Complete xing 1. portable telescopic stick a discharge line 2. The ground product from the distribution 3. Manual 1 4. Product certification 1 choice on how to edit the accuracy and utility grade market universal EMF features are quite different, Some high precision, multi-function, low some precision, simple function. High precision instrument fundamental error (± 0.5% ~ ± 1%) R, precision instrument was low (± 1.5% ~ ± 2.5%) FS, the price difference between 1 to 2 times. Thus the measurement accuracy is not high occasions (such as non-business accounting only abstinence as the goal, but demand for high robustness and excellent repeated occasions) high precision instrument is economically uneconomical. Some models meter claim to have higher accuracy, fundamental errors only (± 0.2% ~ ± 0.3%) R, but there are stringent requirements and a reference to the premise device, such as the case of a temperature of 20 ~ 22 ℃, before and after the straight pipe length requirements discriminate greater than 10D and 3D (mortal to 5D and 2D), and even proposed to the flow sensor is formed integrally with the front straight pipe installed in the flow specification for real-calibration, in order to reduce the impact clamp. So when models do not choose to compare pure look high goals, be specific sample or read the instruction sheet factory do a comprehensive analysis. EMF function of the difference in the market is also a great, simple way to measure the flow rate is only driven by the output analog signal after digital instrumentation; multi-functional measuring instrument has a two-way flow, range switching, the lower limit flow alarm, air traffic control and power cut off the alarm, small signal removal, traffic was significant representation and the total number of accounts, the initiative check and fault diagnosis, and PC communication and active configuration and so on. Some models meter serial digital communication function optional communication interfaces and ASIC (ASIC), to join peace talks HART system, PROFTBUS, Modbus, CONFIG, FF Fieldbus. Conductivity is measured using EMF premise must be electrically conductive liquid, it can not be below the threshold (ie, the lower limit). Conductivity below the threshold measurement error will occur can not even use, even beyond the threshold shift can be measured, thermocouple prices shown little change error Jiangsu, general-EMF threshold at 10-4 ~ (5 × 10- 6) S / cm, depending on the model. Shihai use depends on the flow between the sensor and transducer signal line length and spread capacitor factory in mortal rules apply instruction sheet conductivity corresponding signal line length. Non-contact capacitive coupling large area electrode conductivity meter can measure up to 5 × 10-8S / cm liquid. Conductivity industrial water and aqueous solution of greater than 10-4S / cm, acid, alkali, salt solution conductivity between 10-4 ~ 10-1S / cm, there is no problem using low-grade distilled water 10-5S / cm is no problem. Oil refined and organic solvents do not grams less than the use of low conductivity. Table 1 lists a number of fluid conductivity. From the material found in some pure or solutions conductivity is low, that can not use, but in practice the task will encounter the situation due to the presence of impurities can use, such impurities added conductivity. About aqueous solution, the conductivity of the material is pure water ratio measured in practice rooms, an aqueous solution of practical application can use the ratio of industrial water, conductivity is much higher than Richard, but also conducive to the flow measurement.
