Abstract

The utility model discloses a current digital monitor for a box-type substation three-phase low-voltage control cabinet. The current digital monitor comprises at least one induced transmission device and a display reception device. The induced transmission device transmits detected current and temperature signals to a microprocessor by a current sensor and a temperature sensor, the signals are processed by the microprocessor and transmitted by a wireless transmission module, a wireless reception module of the display reception device receives the signals of the induced transmission device and transmits the signals to a reception microprocessor, the reception microprocessor receives the signals and displays the size of the current and the temperature inside the control cabinet by a display screen, and an operator in charge can get the conditions inside the box-type substation three-phase low-voltage control cabinet based on data parameters displayed on the touch display screen. Thus, the remote digital display of the current and temperature inside the control cabinet is achieved, and the operator can be warned of overcurrent or overtemperature accidents inside the control cabinet.

Description

Case becomes three-phase low-voltage power distributing cabinet current digital type watch-dog
Technical field
The utility model relates to case step-down piezoelectricity flow monitoring equipment technical field, relates in particular to a kind of case and becomes three-phase low-voltage power distributing cabinet current digital type watch-dog.
Background technology
Box-type substation is applicable to residential quarters, the public change in city, bustling downtown area, construction power supply etc., the develop rapidly of Chinese city modernization construction, and the continual renovation transformation of urban power distribution network will extensively be employed.But the electric current of the box type transformer of present use and supporting low voltage liaison net switch board can not carry out real time monitoring, is after grade breaks down, to be overhauled by user notification substantially; Can cause power supply maintenance hysteresiss, device damage rate height, well damage, also can't shift to an earlier date effectively and take precautions against, therefore, press for that the electric current that case change outdoor low voltage is got in touch with switch board carries out automatically, telemonitoring.
The utility model content
The purpose of this utility model provides a kind of case and becomes three-phase low-voltage power distributing cabinet current digital type watch-dog, can realize that remote digital shows to electric current in the switch board and temperature, and can the interior electric current overload of warning operator switch board.
The purpose of this utility model is to be achieved by following technical proposals: a kind of case becomes three-phase low-voltage power distributing cabinet current digital type watch-dog, comprise at least one induced emission device and show receiving device, electric current induced emission apparatus comprises transmission microprocessor, supply unit, current sensor, analog to digital converter, temperature sensor and wireless transmitter module, and described display receiver device comprises accepts microprocessor, wireless receiving module, analog to digital converter, touch display screen and supply unit.
Described supply unit comprises solar panel, solar charging controller and lead accumulator group.
The described microprocessor end of accepting is connected with audible-visual annunciator.
The utility model is to realize like this, show receiving device by installing at duty room, in a plurality of casees changes and switch board, the induced emission device is installed, adopt the utility model of above technical scheme, the induced emission device is by current sensor and temperature sensor, the electric current and the temperature signal that sense are transferred to microprocessor, by by wireless transmitter module signal being transmitted out after the microprocessor processes, after the wireless receiving module of display receiver receives the signal of induced emission device, signal is transferred to accepts microprocessor, after microprocessor receives signal, treated, can show size and the in-cabinet temperature of electric current in the switch board by touch display screen, the operator on duty is according to data presented parameter on the touch display screen, can conveniently understand case and become situation in the three-phase low-voltage power distributing cabinet.Therefore, can realize that remote digital shows to electric current in the switch board and temperature, and the interior electric current of energy warning operator switch board overloads or temperature is too high.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of case becomes three-phase low-voltage power distributing cabinet current digital type watch-dog, comprise at least one induced emission device and show receiving device, electric current induced emission apparatus comprises the transmission microprocessor, supply unit, analog to digital converter, current sensor, temperature sensor and wireless transmitter module, described display receiver device comprises accepts microprocessor, wireless receiving module, analog to digital converter, touch display screen and supply unit, described supply unit comprises solar panel, solar charging controller and lead accumulator group, the described microprocessor end of accepting is connected with audible-visual annunciator.
The utility model is to realize like this, show receiving device by installing at duty room, in a plurality of casees changes and switch board, the induced emission device is installed, adopt the utility model of above technical scheme, the induced emission device is by current sensor and temperature sensor, the electric current and the temperature signal that sense are transferred to microprocessor, by by wireless transmitter module signal being transmitted out after the microprocessor processes, after the wireless receiving module of display receiver receives the signal of induced emission device, signal is transferred to accepts microprocessor, after microprocessor receives signal, treated, can show size and the in-cabinet temperature of electric current in the switch board by touch display screen, the operator on duty is according to data presented parameter on the touch display screen, can conveniently understand case and become situation in the three-phase low-voltage power distributing cabinet.Therefore, can realize that remote digital shows to electric current in the switch board and temperature, and the interior electric current of energy warning operator switch board overloads or temperature is too high.
