The control panel of phase switch internal is connected through conducting wire with clock chip, three relays being connected through conducting wire with control panel according to when
The regular self-test switching of the time of clock chip setting, current transformer of three relays through conducting wire and detection relay switching action
It is connected, current transformer is connected through conducting wire with control panel, and control panel is connected through conducting wire with a communication module, communication module and master control
Device processed is connected.
Preferably, the clock chip is H1410 clock chip.
Preferably, the control panel inside the phase-change switch is RLY_002_0.1 control panel.
The beneficial effect of the utility model using the above structure is that structure is simple, and rationally, phase-change switch can be automatic for design
Detection, after not acted within the set time, phase-change switch itself can carry out automatic commutation in the low power consumption phase, to play
The effect of hidden danger, trouble saving is checked in advance, and phase-change switch can will test information feedback to master controller, master after self-test
Fault message can be notified in time staff by controller, and staff is facilitated promptly to repair replacement failure in time
Equipment plays the role of preventing in advance to will not influence the normal use of equipment.

Specific embodiment:
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with novel.
As shown in Figs. 1-2, a kind of phase-change switch that can prevent detection automatically, the high pressure being connected including one with transformer 1
Inlet wire 2, output end connection A, B, C three-phase power transmission circuit and N phase zero curve of transformer 1, N phase zero curve is through wired earth, in A, B, C
Three-phase power transmission circuit is equipped with a breaker 3 and a measurement mutual inductor 4, measures mutual inductor 4 through conducting wire and 5 phase of a master controller
Even, A, B, C three-phase power transmission circuit is connected through conducting wire with master controller 5, and A, B, C three-phase power transmission circuit are changed through conducting wire with several
Mutually switch 6 is connected, and each phase-change switch 6 is connected through conducting wire with master controller 5 respectively；Control panel 7 inside phase-change switch 6 is through leading
Line is connected with clock chip 8, and three relays 9 being connected through conducting wire with control panel 7 are fixed according to the time that clock chip 8 is set
Phase self-test switching, three relays 9 are connected through conducting wire with the current transformer 10 of detection relay switching action, current transformer
10 are connected through conducting wire with control panel 7, and control panel 7 is connected through conducting wire with a communication module 11, communication module 11 and 5 phase of master controller
Even.
The clock chip 8 is H1410 clock chip.
Control panel 7 inside the phase-change switch 6 is RLY_002_0.1 control panel.
In use, being equivalent to master controller 5 when individual phase-change switches 6 are not operating for a long time and being lost to the state of phase-change switch 6
Gone control, be only defaulted as phase-change switch 6 and rest on some state, and to whether can normal commutation be unknown.And
In the case where in view of high current or when peak times of power consumption on daytime, it is not necessary to frequent commutation power grid can be caused to rush
It hits and three-phase imbalance phenomenon can be made to aggravate, therefore set using the clock chip 8 that 6 inside of phase-change switch is connected with control panel 7
Certain period of time is set, the low power consumption phase is judged, and combine the built-in current mutual inductor 10 of phase-change switch 6, judges low current
Situation, carries out logic judgment by control panel 7, meets the phase-change switch device when simultaneously, (period can within continuous 48 hours
Defined by 10 internal processes of clock chip) it is not operating；Be currently under the low power consumption phase (22 points of night to 5:00 AM, this when
Between section can be defined by control panel 7)；Current flow number very little (is less than 5A), which automatically carries out commutation one by one certainly
Inspection, (the not interactive teletransmission of of short duration commutation data to master controller) is to play the role of checking hidden danger, trouble saving in advance.
When clock chip 8 triggers, control panel 7 controls relay 9 and acts, and detects phase-change switch by current transformer 10
6 whether complete commutation movement, this phase-change switch 6 can by normal use or the information of failure through 7 operation of control panel
Afterwards, master controller 5 is timely fed back to by communication module 11, if the automatic detection information that communication module 11 is fed back is just
Often, it is in good condition to default phase-change switch 6 for master controller 5；If the feedback of communication module 11 is abnormal to automatic detection information, main control
Fault message is notified staff by first time by device 5, goes field maintenance or replacement faulty equipment by staff, thus
The normal use that will not influence equipment plays the role of preventing in advance.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
It protects in range.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
