Description
Technical field
This utility model relates to training on electric power analog, particularly relates to a kind of split type electric energy measuring equipment and terminal installs wiring actual training device.
Background technology
Over nearly 20 years, for overwhelming majority electric energy metrical analog training device or emulation training device, its cabinet is that integral type, its outward appearance and operating table surface electrical energy metering tank true with scene is far from each other, in case, element configuration makes operator imperceptible is on-the-spot electric power meter, relevant metering analog loopback design too complex, high expensive, operation software function is convergent and a lot of function is out-of-date or without practical value, connection type is changeable and inconsistent with scene, operational danger is relatively big, and power consumption is the highest.And, what existing electric energy metrical analog or simulator only laid particular emphasis on on-the-spot false wiring classification arranges function, it is fitted without connection function, bigger with on-the-spot actual metered device difference, the employee or the personnel that transfer that newly work usually lack corresponding practical work experience, scene is not familiar with yet, if training set is inconsistent with field electric energy measurement device, if and the operational approach of training set is inconsistent with the operational approach of situ metrology device, inherently mislead effect, necessarily lose the meaning of training.
It addition, tradition routine training device is a kind of to take an examination especially to identify that examination takes type product as the leading factor, though exercise question quantity is big but of low quality, it is often more important that: not having discrimination between exercise question, out-of-date invalid useless exercise question is more, and it is random that old complexity is deposited in the design of phasor diagram；This utility model is that one is especially trained for leading type product with installation wiring with on-site training, and be closely connected electric energy metrical real work, and instructs real work to train to lead, and is entirely capable of meeting current production technology training many new demands.
Therefore, this utility model had both overcome the shortcoming that in on-the-spot electrical network, electric energy measuring equipment can not arbitrarily arrange fault, on-site training can not be repeated standardized connections training, change again the shortcoming that conventional general Training Simulation Installation presence is not true, practicality is not strong, result of training is the best, allow trainee learn, with (can real work), with then standard (be operated to energy standardization), thus the maximization of result of training can be reached.
Utility model content
The technical problems to be solved in the utility model is the various defects for existing training set, there is provided a kind of from cabinet appearance design, operating table surface design, training function, functional design, wiring technique, production technology, equipment component, current source designs, New technical use, and all many-sides such as drive software all have and break through and the electric energy measuring equipment of innovation and terminal install wiring actual training device.
This utility model solves its technical problem and be the technical scheme is that
A kind of split type electric energy measuring equipment and terminal install wiring actual training device, including with field electric energy measurement bin cabinet in specie, and be arranged in cabinet electric power meter, transformer device, for emulating the data wire of secondary circuit wire, power information acquisition terminal and power supply；It is characterized in that, described cabinet is split type cabinet, and including upper wardrobe body and lower cabinet body, described upper wardrobe body is used for laying electric energy measuring equipment, power information acquisition terminal and test connecting box；Described lower cabinet body is used for laying transformer device；Electric power meter and transformer device in upper wardrobe body and lower cabinet body are connected by data wire, and the junction between data wire and upper wardrobe body and lower cabinet body uses grafting cassette joint；

4. the no-load voltage ratio of convenient actual measurement current transform er；Achieve the actual field verification of current transformer error, the use of on-site calibrator can be trained easily；Achieve once the measurement of (greatly) electric current, the use of clamp on amperemeter can be trained easily.The current all products of this function are the most unrealized, but training and teaching needs " the field-checking function of transformer " in a hurry with qualification work about test.
5. rosette is external, and the mains side of rosette is completely the same with scene with the wiring of load side；Due to major part, manufacturer uses test harness post, and the design of this stage body avoids and frequently uses the rear binding post easily de-disconnected security risk causing open circuit and electric shock.
6. the wiring of transformer secondary side is all consistent with scene, and uses standard connection；The wire that connects used all leaves surplus when installing wiring, but is not connected into spiral shape, electric energy will not be lost, facilitate user rewiring.
The pocket watch backboard of conventional belt electrical analogue platform uses solid iron plate, does not has " wire mesh orifice plate ", it is impossible to carry out installing wiring exercise；This utility model can carry out repeatedly the installation wiring exercise of electric energy meter and acquisition terminal easily.Be conducive to promoting the correct mode of connection simultaneously.
7. in operating table surface, conceal the element and pile crown not used in field electric energy measurement device dexterously, allow only on all four with the scene electric energy measuring equipment and element that user conveniently sees.
8. devise the duty utilizing software to change acquisition terminal in real time, it is achieved that the actual working state that simulated field acquisition terminal is different, increase training of the present utility model and examination function.
9. devise and utilize software real-time operation once or the function such as break-make of secondary voltage, functions such as " in real time stop power transmission " is fully achieved, and stage body power supply need not be closed, not only increase grade of difficulty and the discrimination of examination, and be more nearly on-the-spot real work.
