Abstract
The invention discloses a compound switch auxiliary power supply aiming to provide a compound switch auxiliary power supply which can still normally work when lack phase or cutting of a zero wire occurs in a power supply circuit. The compound switch auxiliary power supply also comprises an input circuit and an inductance coil. The input circuit comprises three capacitors. The three capacitors are of a triangular shape to be connected with power network three phase power supply VA, VB, VC, wherein, two phases are primary connected with a power transformer by the inductance coil, the inductance coil is a double-winding coil with an iron core, the both ends of a primary coil of the power transformer are respectively connected with a winding of the power transformer, and the three phase power supplies are input into the primary winding of the power transformer by the inductance coil after being superposed in a coupling way by the three capacitors. The invention can be widely applied to the technical field of the compound switch.
Description
Technical field
The present invention relates to a kind of combination switch accessory power supply.
Background technology
Because magnetic latching relay and A.C. contactor are in operation and usually are subjected to the influence of reactance factor in circuit or the load, main contact the time is easy to generate electric arc inevitably in a deciliter action, this electric arc gently then damages the contact and causes switch deciliter bad, reduces the reliability and the useful life of equipment; Heavy then cause the arc short circuit accident, jeopardize equipment and personal safety.The birth of combination switch has solved this problem effectively, make the use of combination switch day by day expand, but, because the present accessory power supply of combination switch is on the market taken from the single-phase or two-phase power supply of electrical network mostly, in power supply circuits generation phase shortage or disconnected zero time, the accessory power supply of combination switch will interrupt like this, and combination switch is with regard to cisco unity malfunction, therefore, combination switch accessory power supply of the prior art exists in power supply circuits generation phase shortage or the disconnected defective of cisco unity malfunction zero time.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of at power supply circuits generation phase shortage or disconnected combination switch accessory power supply that still can operate as normal zero time.
The technical solution adopted in the present invention is: the present invention includes power transformer, full-wave rectifying circuit, filter circuit, + 5V voltage-stabilizing output circuit, + 12V output circuit, it also comprises input circuit and inductance coil, described input circuit comprises three electric capacity, described three electric capacity connections triangular in shape and with electrical network three phase mains VA, VB, VC connects, wherein two-phase is connected with the elementary of described power transformer by described inductance coil, described inductance coil is the double winding coil that has iron core, each is connected the primary coil two ends of described power transformer with a winding of described inductance coil, three phase mains is imported the elementary winding of described power transformer via three capacitively coupleds stack back by described inductance coil, exports described full-wave rectifying circuit to by described power transformer secondary, filter circuit, + 5V voltage-stabilizing output circuit, + 12V output circuit.
The invention has the beneficial effects as follows: because the present invention also comprises input circuit and inductance coil, described input circuit comprises three electric capacity, described three electric capacity connections triangular in shape and with electrical network three phase mains VA, VB, VC connects, wherein two-phase is connected with the elementary of described power transformer by described inductance coil, described inductance coil is the double winding coil that has iron core, each is connected the primary coil two ends of described power transformer with a winding of described inductance coil, three phase mains is imported the elementary winding of described power transformer via three capacitively coupleds stack back by described inductance coil, so the present invention has in power supply circuits generation phase shortage or disconnected advantage that still can operate as normal zero time.
