The developed digital display thermal relay motor protector calibrator adopts advanced control technology in design, so that the instrument is easy to operate when it is used. The instrument has the characteristics of reliable and stable performance, intuitive and fast readings, accuracy of test data, simple operation and convenient use. Users only need to connect the test cable to directly perform the calibration work, without the need for additional voltage and current regulators, monitoring current and voltage meters, current and voltage converters and complex wiring.
① There are two gears for timing to meet the needs of long-term or instantaneous timing, the first gear: 0.0000S ～ 999.9999S; the second gear: 0.00S ～ 9999.999S; three-phase output 0-50A-100A-150A-200A- The 500A three-phase instrument can be tested simultaneously in three phases and can also be adjusted in phases. And can record the action time synchronously with the judgment of normally open and normally closed contacts.
②The multi-function digital LED is used to display I and U meters, the reading is intuitive and the precision is high.
③The output and monitoring of AC voltage 0 ~ 450V and DC voltage 0 ~ 250V are added to meet the operation characteristic test of various AC and DC voltage relays and AC contactors and the verification of AC and DC voltage meters; the operation time can be recorded synchronously with constant Discrimination of open normally closed contacts.
④Adopt a beautiful aluminum alloy case with flip cover, with handles on both sides of the case for on-site movement.
⑤Imported components are used to make the instrument with extremely strong load-bearing capacity, and a more complete electrical protection circuit is added, which can be connected in series for simultaneous verification. Greatly improve the verification efficiency.
⑥ Increase the output current to adapt to the setting of commonly used current and increase to multiple output current to adapt to the detection of various commonly used electrical appliances. Corresponding improvements have been made to other structures, the functions are more complete, it provides convenience for use, simplifies the operating procedures, and is more suitable for on-site use.
Electrical equipment has protection devices, commonly used are motor protector devices, thermal relays, current relays, voltage relays, fuses, circuit breakers. Some parameters of long-term protection of electrical appliances will deviate from the original setting values due to thermal deformation, corrosion, looseness, and long-term overload. There are serious failures and inactions. This loses the protective effect that the protective device should have. In order to solve the above problems, a series of setting and calibration instrument products have been developed and produced-a series of single-phase and three-phase digital display multi-function thermal relay motor protector calibrators to adapt to different industries such as power plants, chemicals, metallurgy, coal It is used in different test fields and test environments such as laboratory, mobile use on site.
This product is used for the distribution protection device of electrical equipment, the setting and testing of switch and electrical appliances, the whole group test of transformer, distribution panel and cabinet. This instrument is a series of products with various specifications, which can be applied to various industries such as metallurgy, electric power, machinery, textile, power generation, chemical industry, transportation service and so on. This instrument is small in size and easy to carry. It can test, set, and accept various protective appliances such as circuit breakers, semiconductor circuit breakers, thermal relays, electronic motor protectors, etc. in the laboratory and on-site. It is suitable for small workshops. This instrument can also verify current meters, voltmeters, current transformers, clamp meters, etc. commonly used by electricians. It can also be used for AC contactor pull-in, release characteristics, detection, adjustment, contact heating test, fuse fusing test, etc.
