If the electricity testing and phase checking device of the high-voltage cabinet, which has a simple structure and low cost and is convenient to operate by one person, can be designed, the problems can be well solved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, low cost and be convenient for the single-person operation's high-voltage board test electricity nuclear phase device.
The utility model adopts the technical proposal that: the utility model discloses a casing, button, power module, MCU control module and display module, power module with MCU control module all sets up in the casing, MCU control module with the power module electricity is connected, the button with display module all sets up on the panel of casing, display module includes first electrified lamp, the electrified lamp of second and power indicator, the button passes through power module with power indicator electricity is connected, first electrified lamp passes through MCU control module tests the electricity with the first of high-voltage board and holds the electricity and be connected, the electrified lamp of second passes through MCU control module tests the electricity with the second of high-voltage board and holds the electricity and be connected.
It is apparent from the above-mentioned scheme, the utility model is suitable for a high-voltage board of 10KV-20KV circuit, when pressing the button, power indicator often is bright, then represents switch on, the utility model discloses normal work loosens the button otherwise, and power indicator extinguishes, the utility model discloses stop work. When the utility model discloses normal during operation, if the first electricity end of testing of high-voltage board or the second tests the electricity end circular telegram, then the first electrified lamp that corresponds or the electrified lamp of second will flash light, show that the electricity end of testing that corresponds has circular telegram. Therefore, the utility model is not only simple in structure, only can detect the existence of whether high-voltage board has a voltage moreover through pressing the button, still easy operation is convenient, the human cost that has significantly reduced.
Furthermore, display module still includes heterogeneous lamp and homophase lamp, heterogeneous lamp passes through MCU control module tests electric connection with the first of high-voltage board, the homophase lamp passes through MCU control module tests electric connection with the second of high-voltage board. Therefore, when the utility model discloses normal operating, if the line phase difference of two electroscopic ends is less than +/-30, the lamp will flash light of same phase, if the phase difference is more than +/-40, the lamp will flash light of out of phase.
Further, the display module further comprises a buzzer, and the buzzer is electrically connected with the first electricity testing end of the high-voltage board through the MCU control module. It follows that if the phase difference is above +/-40 deg., the out of phase lamp will flash and the buzzer will also sound intermittently.
Further, be provided with first wiring port and second wiring port on the panel of casing, first electrified lamp passes through MCU control module with first wiring port electricity is connected, first wiring port passes through first connecting wire and the first electricity end electricity of testing of high-voltage board and is connected, the electrified lamp of second passes through MCU control module with second wiring port electricity is connected, second wiring port passes through the second connecting wire and tests the electricity end electricity with the second of high-voltage board and is connected.
