Embodiment
Below more in conjunction with the accompanying drawings embodiment the utility model is specifically described.
As shown in Figure 1, high-voltage power metering case remote control meter copying device can be made the usefulness of outdoor high-voltage electric energy metrical in the distribution system of the three-phase alternating current 50HZ of 10KV electric pressure.It is installed on electric pole 2 and the support 4, electric energy metering box 3 and the digital display device 5 installed by the high-voltaghe compartment 1 that is provided with two high precision dry-type voltage inductor PT, two current transformer CT, with the high-voltaghe compartment disjunctor are formed, and its voltage transformer pt summation current transformer CT all can reach 0.2 grade of accuracy rating.The meter reading personnel can be at a distance by the telepilot work of checking meter, the data of electric energy meter can show on digital board.
As shown in Figure 2, high-voltaghe compartment 1 has the casing 10 of a sealing, this casing comprises the underframe 8 that can be connected with support 4, this underframe and casing solid welding one, case lid 6 is detachable fixing with casing, both faying faces are provided with sealing gasket 7 sealings, adopt air combined insulation in the high-voltaghe compartment casing, energized conductor is all sealed with insulating material, be provided with two voltage transformer pts and two current transformer CT of connecting by V/V in the casing, high-voltage connection terminal three advances three and goes out that totally six terminals are located at the case lid top, by 12 insulation of six high pressure silicone rubber composite bushings, the lower end isolates with special-purpose epoxy resins insulation block 11 protection, makes energized conductor totally-enclosed.At the bottom of high-voltaghe compartment, be provided with air filter 9 and be double-deck air purifier, have dry, dirt eliminating function, fundamentally solved condensation problem.
As shown in Figure 3, three-phase three-wire electric energy meter, batch meter voltage transformer (VT), current transformer, digital display device are connected by associating terminal box 1-9 connection terminal.Secondary circuit is directly guided in the electric energy metering box 3 in casing 10 after being fixed by insulation hard tube sheath, and rainproof bright lock is installed on the electric energy metering box, and its chamber door is provided with the transparent inspection window of glass.The working power of digital display device 5 is provided by voltage transformer secondary, be arranged on the bottom of electric energy metering box 3, its signal leads to the display screen PORT COM from the RS485 PORT COM of electric energy meter, electronic circuit is by Single-chip Controlling, the meter reading personnel sends signal by the Digiplex TX315 in the hand, after the digital board of table in the case receives signal, the data in real time of multifunctional meter is reflected to wiring board and shows by charactron.The display board center is controlled to be the AT89C52PI single-chip microcomputer.After remote controller TX315 receives signal, begin to trigger AT89C52PI work, and enter self check from returning to form, after remote control receiver module TX315 receives first signal, in 5 seconds, as there is not a secondary signal input, single-chip microcomputer will read in the internal memory of oneself by RS485 data acquisition mouth, and submit the total data reception to multifunctional meter and instruct, display module will demonstrate relevant data every 5 seconds on the digital display tube in high definition, till demonstration finishes, during this period if any second signal input, then be as the criterion, show corresponding data by second signal input.
