Abstract
The invention discloses a high-voltage electrified display with electricity checking and phase detection functions. The high-voltage electrified display comprises display lamps Da, Db and Dc which are connected with an A-phase high-voltage end, a B-phase high-voltage end and a C-phase high-voltage end respectively, wherein the display lamp Da is connected in parallel with an A-phase electricity checking hole Ka; the display lamp Db is connected in parallel with a B-phase electricity checking hole Kb; and the display lamp Dc is connected in parallel with a C-phase electricity checking hole Kc. During actual running, an electricity checker can be used for directly performing secondary electricity checking confirmation on the electricity checking holes, so safety accidents are avoided greatly; and if two power supplies supply power on a user site, phase detection is realized through the formed electricity checking holes, and great conveniences are provided for users.
Description
Technical field
The present invention relates to a kind of high-voltage charge display device, especially a kind of easy to use, can stop the high-voltage charge display device with electrical verification nuclear phase function of security incident.
Background technology
High-voltage charge display device is applied to High-Voltage Electrical Appliances cashier's office in a shop usually, be provided with respectively the pilot lamp that joins with high-pressure side (A, B, C), when high-pressure side curtage signal is high pressure, pilot lamp is bright, charged with the reaction high-pressure side, and by be installed on high-voltage board on electromagnetic lock cooperate, realize the function of forced blocking.But existing high-voltage charge display device there is no electrical verification nuclear phase function, if luminous indicating lamp has fault, single-phase or three-phase pilot lamp does not show the indication that promptly can make the mistake, thereby generation security incident during high pressure.
Summary of the invention
The present invention is in order to solve the above-mentioned technical matters of existing in prior technology, to provide a kind of easy to use, can stopping the high-voltage charge display device with electrical verification nuclear phase function of security incident.
Technical solution of the present invention is: a kind of high-voltage charge display device with electrical verification nuclear phase function, display lamp Da, the Db or the Dc that join respectively with A, B, C three-phase high-voltage end are arranged, it is characterized in that: be parallel with A electrical verification hole Ka mutually with display lamp Da, be parallel with B electrical verification hole Kb mutually with display lamp Db, be parallel with C electrical verification hole Kc mutually with display lamp Dc.
The present invention is in actual motion, can use electroscope that the secondary electrical verification is directly carried out in the electrical verification hole and confirm that the generation of having stopped security incident greatly is if the user scene is a dual power supply, also can realize nuclear phase, greatly facilitate the user by set electrical verification hole.
Description of drawings
Fig. 1 is the circuit theory diagrams of the embodiment of the invention.
Fig. 2 is the external structure synoptic diagram of the embodiment of the invention.
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.As shown in Figure 1, 2: display lamp Da, the Db or the Dc that join respectively with A, B, C three-phase high-voltage end are arranged, the output that is each high-pressure side is joined with display lamp Da, Db or Dc by the filtering circuit that resistance, electric capacity constitute, whether charged, display lamp Da, Db or Dc adopt long-life, high brightness LED if reacting high-pressure side.Different is to be parallel with A phase electrical verification hole Ka with display lamp Da with prior art, is parallel with B electrical verification hole Kb mutually with display lamp Db, is parallel with C electrical verification hole Kc mutually with display lamp Dc, can carry out electrical verification and nuclear phase.
Claims (1)
1. high-voltage charge display device with electrical verification nuclear phase function, display lamp Da, the Db or the Dc that join respectively with A, B, C three-phase high-voltage end are arranged, it is characterized in that: be parallel with A electrical verification hole Ka mutually with display lamp Da, be parallel with B electrical verification hole Kb mutually with display lamp Db, be parallel with C electrical verification hole Kc mutually with display lamp Dc.
