Abstract

The utility model relates to a power supply on/off operator with a long distance remote controller, which consists of a fixed-frequency receiver, a low-voltage auxiliary power supply, a control relay coil and a power supply contactor, and adopts the power supply contactor of the prior art. The low-voltage auxiliary power supply which can control the action of the relay coil is arranged additionally between the fixed-frequency receiver and the control relay coil so as to control the opening and closing of the normally opened contact and the normally closed contact of the relay coil thus controlling the power supply contactor. A circuit consisting of a No. 1 fixed-frequency receiver is used as a transmission line. When the No. 1 fixed-frequency receiver receives information, the circuit is connected, or the circuit is disconnected. If the technology of the utility model is used, when the circuit goes wrong, after reparation, the closing transmission can be achieved timely; and when the circuit goes wrong, the power supply can also be disconnected timely. The utility model can also be applicable to the control of the opening and closing of the circuit of the vehicle, and can disconnect or connect the power supply circuit in a remote-controlling way, thereby preventing or stopping theft and stopping the abnormal operation of the vehicles.

Description

Electric operating means is sent in a kind of power failure of being furnished with the long-distance remote control device

Technical field: the utility model relates to mains switch, relates in particular to a kind of power failure of being furnished with the long-distance remote control device and send electric operating means.

Background technology: the mains switch of adapted in the mains switch of prior art, the especially substation, after the fault earthing tripping operation that is short-circuited, generally all can automatic closing.But close a floodgate continuously after three times, once more automatic closing.At this moment, operating personnel must arrive on-the-spot, with manually operated form, realize closing a floodgate once more.In some cases, allow the operating personnel scene of arriving in the very nick of time be unusual difficulty, sometimes or even impossible.This just may result in greater loss because can not in time send electricity, and perhaps can not in time have a power failure enlarges device damage.

The purpose of this utility model is, overcome the deficiencies in the prior art part, provide a kind of power failure of being furnished with the long-distance remote control device to send electric operating means, adapt to distribution transformer, with remote audio signal, pass through conversion equipment, realization is to the long-distance remote control of mains switch, both remote power-ofves at any time, also remote control turn-on power at any time, replace manual operation, so that outage or in time close a floodgate and send in time.

Summary of the invention: electric operating means is sent in a kind of power failure of being furnished with the long-distance remote control device described in the utility model, include No. 1 fixed frequency receiver, No. 2 fixed frequency receivers, low pressure accessory power supply, control relay coil and power contactors compositions, said No. 1 fixed frequency receiver and No. 2 fixed frequency receivers, structurally basic identical, just different in wiring.Said power contactor is exactly the power contactor of prior art.Said No. 1 fixed frequency receiver and No. 2 fixed frequency receivers, the low pressure that is connected in series accessory power supply and control relay coil, control relay moment adhesive normally opened contact or normally-closed contact are connected the contactor of controlling power supply again.Said No. 1 fixed frequency receiver and No. 2 fixed frequency receivers, it can be the information receiver of the fixed frequency of prior art, such as the beeper that can be prior art, use the lower power supply of beeper output, as the signal source and the power supply of drive controlling relay coil.Certainly when making product of the present utility model, here be not to use existing beeper, but can use the circuit of existing beeper or the circuit board of existing beeper, the roughly the same circuit board of basic function that also can design a kind of beeper of and prior art gets final product.Not enough for preventing the power supply energy of exporting by the information receiver of fixed frequency, can constitute an amplifying circuit with triode, perhaps with the signal out-put supply of fixed frequency receiver, one of adjunction can make the power supply of control relay coil adhesive action again, form a low pressure accessory power supply, connect the control relay coil, adhesive normally opened contact or normally-closed contact, connect the contactor of control mains switch again, and then finish folding control procedure mains switch.The characteristics here are, in the front of power contactor, are provided with a control relay, with control relay coil moment adhesive normally opened contact or normally-closed contact, realize the control to power contactor.The circuit that said No. 1 fixed frequency receiver constitutes uses as power transmission sequence, and when No. 1 fixed frequency receiver received information, to be that the normally opened contact of little relay is instantaneous be converted to normally closed form with control relay.Energized, at this moment the normally-closed contact of power contactor constitutes the loop, makes the contactor adhesive.Said No. 2 fixed frequency receivers use as dead line, and when No. 2 fixed frequency receivers received information, control relay was that the normally-closed contact of little relay becomes normally open.At this moment, the normally off that contactor becomes when sending electricity has become the state of often opening again, thereby has made the coil blackout of contactor, can not the closed-loop path.

Use a kind of power failure of being furnished with the long-distance remote control device described in the utility model to send electric operating means, adapt to distribution transformer, can break down at circuit, during earth leakage or short circuit tripping operation, after the staff repairs, the electrician personnel can in time realize closing a floodgate and send under the situation that need not enter switchgear house.Also can be when breaking down, deenergization is in time avoided as much as possible or is reduced because of having a power failure or because the loss that can not in time have a power failure and may cause.Electric operating means is sent in a kind of power failure of being furnished with the long-distance remote control device described in the utility model, also control applicable to the folding of vehicle circuit, stop sending electric operating means to be installed on the position that vehicle circuit individual is not easy to change with of the present utility model, in the power supply storage battery such as vehicle, can use the power circuit of the mode conducting vehicle of remote control, also can disconnect the power circuit of vehicle with the mode of remote control, reach prevention or stop the purpose of stealing, stoping the vehicle abnormal running.
