Portable power meter calibration device to talk about the application and management

Transformer requires the ability of anti-electromagnetic interference,[link widoczny dla zalogowanych], can be used under wide temperature conditions, the impact of temperature on the inspection error and small. Although the development of this type of portable calibration device hanging very necessary.. 8. Has produced a portable calibration device,[link widoczny dla zalogowanych], its structure and test procedures referred to similar and dissimilar devices, such as several. Based on years of analysis of the inspection of portable devices, there are some common problems, single-phase portable devices are: ① the phase adjustment range below standard, some with only 0.5 (c) file, no phase fine-tune, no phase monitoring. Mainly the current error @ start, or the most low-end current transformers do not meet the requirements. ⑧ voltage. The larger current loop interaction . ④ Some current transformer is not configured, the current test point can not be adjusted. In addition to the three-phase portable device also exists the above problems, three-phase voltage, current and phase symmetry can also poor. In JJG597 \ assessment , only the standard form. Table for monitoring the amount of testing carried out even if the transmission. Now, in addition to a small number of units of a new share of the 0.8 standard in portable device applications to build on the general economic conditions are poor, can not afford to purchase the unit fixed calibration device, sometimes also gave the green light metering sector. In short, the management of portable devices more chaos, not be specified. IV. Suggestions 1. In summary, the field energy meter testing and the use of portable devices has already started that the agenda, recommended that the competent authorities in this regard to do experimental work, knot homemade instruments available energy metering. Portable device puts forward the technological level of technical and management requirements. If the above are on a Velvet ■ jI account online measurement technology, but also group,[link widoczny dla zalogowanych], testis I1 Bei, salute, AC two-speed elevator computer controller I / l from Li Zhang of Anhui Mechanical and Electrical Engineering, Tang heap silly. /. q J state who operate in Wuhu Yuan Tong Ting Wang Si L / / ABSTRACT This article describes the play developed with single chip micro-computer exchange of two-speed elevator dedicated controller and controller components and basic software fault position display system, online testing,[link widoczny dla zalogowanych], parameter setting and reliability are briefly described. First, the photo above more than 2OO domestic elevator manufacturers, but imports only a few plant reference PC (programmable controller) control, or communicate with the PC to achieve voltage control. Or the whole computer-controlled variable speed AC transformer (VVVF) system. With economic development, the elevator will be increasing demand for, technical transformation lift increasingly heavy task. In order to meet development needs, the author developed into a dedicated controller (SPC) are described below. =, SPC control basic control of La Xiao Tian Beng transfer space elevator is a mechanical and electrical integration of vertical transportation equipment, currently part of this design should be safe and reliable elevator controller steady, stop level accuracy and efficiency as the main technical indicators. Elevator service for the management and operation process,[link widoczny dla zalogowanych], SPC controller is the mission established by the different functional modules, then the conditional connection. Security system in the elevator car door closed and the car lift electric drive system, there are hall calls and car service within the layer selection system. The function of this module has established solid 1SPC car door controller controls the basic transfer of solid, car lift control, online location to pick test, online exchange rate, call the registration line online consumer numbers, online spot emergency treatment, self-diagnosis. Figure 1 is to register two types of SPC control limits of error to the scene to examine the provisions, which need to make a lot of tests and statistics. 2. The original 0.6 portable devices should be prohibited because there was no transformation of the value of the amount of mass carried out. User newly acquired 0.8 portable device should be strictly in accordance with order requirements, in its examination under standard conditions, the Taiwan grid, but also assessing the basic character sets in use of procedures required under the conditions provided in order to allow the construction standards; If the actual load conditions for the test. The actual situation at present, should not be built temporary standard. For existing O. Eight fixed on bamboo mat installation 19a5 home and because the acquisition of five portable devices 0.8 units to 0.8 should be fixed as the device as standard on the construction of n. Eight out of order for the requirements of portable devices can be used as auxiliary criteria, in addition to allowing for the first type described earlier site inspection of the outside (to the force of law), also allows for the real load conditions on-site inspection, but only as The crude was seized power meter measurement picking experience. 8. Digestion and absorption of foreign advanced meter more field testing equipment and management experience. Domestic development of such equipment. Work to meet the energy measurement of the actual needs. ~ Rainbow a
