Embodiment
Below in conjunction with drawings and Examples, content of the present utility model is described in further detail:
Be the outside drawing of combined intelligent terminal connection box and integral and intelligent connection plug as Fig. 1 and Fig. 2, combined intelligent terminal connection device changes the table plug by combined intelligent terminal connection box, integral and intelligent connection plug and safety-type and forms, combined intelligent terminal connection box is installed in transformer station's measuring screen cabinet, top terminals 1 are connected with the charging gate energy meter, read the signals such as voltage, electric current, pulse, communication, bottom terminals 2 are connected with the substation secondary measurement loop, transfer overvoltage, current signal, the centre is the multi-cable socket 3 that is connected with plug.have 10 groups of double-reed in the multi-cable socket 3 of combined intelligent terminal connection box, the double-reed of multi-cable socket divides two of up and down, be bent into respectively former and later two surface of contact, the up and down reed is by former and later two surface of contact conductings, the integral and intelligent connection plug comprises plug 6, terminals 7 and safety screen 8, the terminals of integral and intelligent connection plug are connected to existing calibration device by cable, when being inserted into terminal box, completes by plug voltage, the conversion of current return, guarantee not short circuit of voltage circuit, current return does not open circuit, and the whole dead electricity of terminal box top terminal, can make device security and carry out field-checking, to guarantee device security and the personal security of changing table handling.Have 10 groups of two-man act contacts in combined intelligent terminal connection box, two parts up and down of every group of contact all are in conducting state in normal operating conditions, can directly flow to the three-phase gate energy meter through contact from the voltage and current signal in the secondary measurement loop.
The below will further illustrate by example the principle of work of combined intelligent terminal connection device:
When the three-phase gate energy meter is carried out field-checking:
A) transmission of voltage signal
Parallel way is adopted in the field-checking collection of voltage signal, voltage signal is connected in parallel to voltage input end of on-site calibration device, the terminal of integral and intelligent connection plug during insertion, upper and lower two copper sheets are in parallel by the voltage shorting stub, and the voltage input end that is passed to existing calibration device is sub, successively back down forward and backward double reed sheet structure simultaneously, this structure makes voltage signal be passed to all the time gate energy meter, also makes on-site calibration device can collect voltage signal.Whole process voltage signal is in connection status (not short circuit of voltage) all the time.
B) transmission of current signal
Series system is adopted in the field-checking collection of voltage signal, voltage signal is connected serially to voltage input end of on-site calibration device.The terminal of integral and intelligent connection plug during insertion, upper and lower two copper sheets are connected to respectively electric current input, the lead-out terminal of on-site calibration device by wire, wherein: when copper sheet backs down first group of double-reed, current signal branches to on-site calibration device, second group of double-reed keeps in touch, and keeps gate energy meter normally to obtain current signal; Plug continues to insert forward, and copper sheet backs down second group of double-reed, and this moment, current signal all switched to on-site calibration device, then flowed to gate energy meter, and gate energy meter and on-site calibration device still remain and obtain current signal.Whole process current signal is in connection status (electric current does not open circuit) all the time.
The three-phase gate energy meter is done when changing table handling:
The transmission safety-type of voltage signal changes no-voltage shorting stub in the table plug, upper and lower two copper sheet spares are in insulation, off-state, after plug inserts combined intelligent terminal connection box, the lower end in contact of only having lower copper sheet and front and back double-reed, maintain the voltage signal from the secondary measurement loop, and upper copper sheet to three-phase gate energy meter end is in off-state, without any voltage signal, guaranteed that operating personnel do not have any electric shock risk when the loading and unloading gate energy meter need to be twisted the metal screw, guaranteed personnel's life security.The current return that safety-type changes in the table plug has the electric current shorting stub, and its effect is the switch current loop.Normal operation is to enter from the current signal in the secondary measurement loop current input terminal subflow from combined intelligent terminal connection box, current input terminal to the three-phase gate energy meter, then flow back into the secondary measurement loop from the lead-out terminal of gate energy meter through the compound terminal Intelligent wiring box, whole loop is a complete electric current loop.Therefore when changing table handling, the current signal three-phase gate energy meter of no longer flowing through, only flow through from combined intelligent terminal connection box inside, under the electric current input and output terminal of showing plug, copper sheet uses the short circuit current line to connect so security is changed, make can the road from secondary measurement current signal pass through from here, top to the part of gate energy meter all disconnects.In whole process, the secondary measurement loop current signals is in connection status (electric current does not open circuit) all the time.
