[0002] Electric energy metering and testing is an important technical foundation for economic activities, national defense construction, scientific research and social development. Through the transfer of measurement benchmarks and standard values, the testing laboratory completes the accurate measurement and verification of various metering products. The detection scope includes voltage, current, power, frequency, etc. to meet the needs of modern electricity meter verification technology, and also covers other metering needs such as gateway electricity meters and energy metering electricity meters. However, in the full performance test and inspection of electricity metering equipment, there are still problems such as inconsistent business processes, low detection efficiency, and blind spots in management and control. As an important part of quality supervision, the full performance test and inspection of electricity metering equipment has large differences in its work flow, detection plan, and test methods, which cannot meet the timeliness requirements of detection work, and there is still a lack of effective and objective evaluation methods for operating efficiency and application level.

[0003] At present, the development of electric energy metering equipment detection technology cannot fully match the actual application needs, which is mainly manifested in: 1) isolated detection schemes are only for single metering products; 2) detection items can only be detected sequentially, and parallel or multi-item combination detection of multiple detection items is not reflected in the detection process; 3) in the laboratory testing environment, it is impossible to simulate the performance detection of various environmental stresses superimposed in actual applications. Utility Model Content

[0004] The utility model aims to provide an integrated electrical measurement and detection laboratory to solve the problem of low detection efficiency caused by only isolated detection in the current electric energy measurement and detection process.

[0009] Furthermore, the interval between the devices in each performance detection area is greater than a set distance to avoid mutual interference between the detection devices.

[0010] Since the detection equipment in each detection area will generate electrical environmental interference such as strong magnetic field, instantaneous pulse large current, instantaneous pulse high voltage, etc. during the test, the utility model arranges the equipment at a certain interval.

[0015] Furthermore, the performance detection area includes an electromagnetic compatibility detection area, and the detection equipment arranged in the detection area includes an AC magnetic field influence test device, an electromagnetic radiation test device and an electric energy meter signal tester.

[0016] The utility model realizes detection of different performances in different detection areas and realizes detection of the same performance in the same detection area by setting five different detection areas.

[0025] The specific implementation of the utility model will be further described below in conjunction with the accompanying drawings.

[0026] The integrated electrical measurement and testing laboratory includes an integrated testing laboratory management area and different performance test areas. Each performance test area includes an inlet for the equipment to be tested, an outlet for the equipment to be tested, and test equipment that is arranged in the area and adapted to the performance test area. A transmission channel is arranged between adjacent test equipment in each performance test area to transmit the equipment to be tested between the test equipment to form a test line. The test process in each test area is set and controlled through the integrated testing laboratory management area.

[0027] Specifically, the test areas set in this embodiment include five types, including type test test area 1, electrical performance test area 2, environmental test test area 3, mechanical performance test area 4 and electromagnetic compatibility test area 5, and corresponding test equipment is set in each test area. Figure 1 As shown, the testing equipment provided in the type test detection area 1 includes a pulse voltage test device 101, a surge current test device 102, a first overcurrent test device 103, a second overcurrent test device 104 and a load current transient tester 105; Figure 2 As shown, the detection equipment set in the electrical performance detection area 2 includes a single-phase smart energy meter calibration device 201, a three-phase smart energy meter calibration device 202, an energy meter function tester 203, a communication protocol consistency tester 204 and a three-phase smart energy meter calibration device 205; Figure 3 As shown, the testing equipment provided in the environmental test detection area 3 includes a glow wire test device 301, a sunlight radiation test chamber 302, a dust test chamber 303, a mold test chamber 304, a high and low temperature alternating damp heat test chamber 305 and an electric energy meter terminal temperature tester 306; Figure 4 As shown, the testing equipment provided in the mechanical performance testing area 4 includes a vibration test bench 401; Figure 5 As shown, the detection equipment set in the electromagnetic compatibility detection area 5 includes an AC magnetic field impact test device 501, an electromagnetic radiation test device 502 and an electric energy meter signal tester 503.

[0031]

[0032] The detection equipment in each detection area is set up in a similar manner. The detection equipment in each performance detection area is arranged in two rows. An artificial channel for detection personnel to pass through is set between the two rows. A transmission channel is set between any two adjacent detection equipment in each row to transmit the equipment to be tested between the detection equipment. The ends of the two rows are also connected by a transmission channel to form a detection assembly line, which is convenient for the automatic flow of equipment to be tested in the detection area, realizes the automation of metrology and calibration, greatly improves the space and time efficiency, and reduces the proportion of labor costs.

[0033] The conveying channel is a roller slide. To facilitate the equipment to be inspected to enter or flow out of the inspection area, a roller slide is set between the inlet of the equipment to be inspected and the inspection equipment at the inlet of the equipment to be inspected, and a roller slide is set between the outlet of the equipment to be inspected and the inspection equipment at the outlet of the equipment to be inspected.

[0034] As another implementation method, it can also be understood that the detection area is divided into a U-shaped structure by a transmission channel, the middle of the U-shaped structure is an artificial channel, and the detection equipment is arranged along the extension direction of the transmission channel. Since the detection equipment in the detection area will generate strong magnetic fields, instantaneous pulse large currents, instantaneous pulse high voltages and other electrical environmental interference during the test, the distance between the detection equipment in each detection area is required to be greater than 3 meters to avoid any impact.

[0035] Transmission channels can be set up between detection areas according to actual conditions. If the detection areas are arranged on the same floor, transmission channels can be set up between the detection areas. If they are not on the same floor, the flow will be determined according to actual conditions.

[0036] Each test area is an independent test unit, and its test sequence is not limited to the test sequence of the test area number, and the test areas can be freely combined. The various types of test equipment in the test area are independent test equipment, and their test sequence is not limited to the test sequence of the internal number of the test area, and the test equipment can be freely combined. The division of the test area is determined by the functional attributes of the test equipment. The test items in the type test test area are high voltage and high current detection, and the insulation protection requirements are high; the test items in the electrical performance test area are full performance tests, communication protocols and other normative function tests; the test items in the environmental test test area include smoke, burning, high and low temperature, humidity and other simulated external environment tests, and smoke exhaust pipes, drainage pipes and other facilities can be set up as needed; the mechanical performance test area is a vibration test, and it should be arranged on the first floor as much as possible and the ground needs to be hardened; the electromagnetic compatibility test area test items are strong magnetic and signal detection, and it should be as far away from other test areas as possible.

[0037] When setting up the testing area, try to install testing equipment with similar testing items in the same testing area. The location of the testing equipment in the testing area can be reasonably arranged according to the actual situation of the testing laboratory house, and the chassis base of the testing equipment is mostly equipped with casters for easy movement. There are many types, categories and models of electrical measuring equipment. The testing process will change according to different electrical measuring equipment, and can be adjusted according to the new testing process.

[0038] In order to facilitate the management of the entire testing process, this laboratory also has an integrated testing laboratory management area 6, such as Figure 6 As shown, a wall is set between the management area and the testing area to separate the testing area and the management area to avoid mutual interference. The management area is provided with a server 601, a desktop terminal 602, a printer 603, a barcode scanner 604 and a testing tool 605. The metering product to be tested is provided with a barcode. The laboratory testing personnel place the metering product to be tested on the testing tool, scan the barcode with a barcode scanner, enter the number, model and other parameters of the metering product to be tested, and then set the testing process and testing items.

[0039] The metered products to be inspected enter the inspection area through the inlet of the inspection equipment, and after being inspected in sequence, they flow out from the outlet of the inspection equipment, forming an inspection line in the inspection area, saving space and speeding up the inspection efficiency. All inspection processes, inspection data, etc. are stored in the server 601 of the integrated inspection laboratory management area 6.
