Abstract
The utility model relates to a remote-controlled ac power supply switch, comprising a signal projector and a power controller arranged in a terminal box on which a signal receiving device receiving the control signal from the signal projector and connecting or cutting off the power supply is arranged. The power controller is connected in series to a live wire or a zero line, which are not needed to be together connected to the terminal box, and the power controller is also provided with a manual switch device, and a dc power supply needed when the signal receiving device works normally, which can supply power to the signal receiving device no matter the ac power supply controlled by the power supply is connected or disconnected. The benefit effects of the utility model are as follows: the interchangeability of the utility model and the ordinary power supply is ensured, the manual switch device can independently control the connection or the disconnection of the power supply, and an operator can complete the remote control of the connection or disconnection of the power supply by the signal projector.
Description
Technical field
The utility model relates to the power switch technology, mainly relates to a kind of ac power switch of Long-distance Control.
Background technology
The power switch of general control on/off needs the operator to go installation switching device to realize the break-make of power supply near power switch.If requiring has two places can control the break-make of a power supply, then need to adopt ganged switch and complicated wiring to realize, if require the break-make of the power supply of ground point control more than two, then wire structures will be complicated more.1), need the operator to control the break-make of power supply near power switch the shortcoming of its structure is:; 2), by the break-make of a power supply of reference mark control with by the break-make of a power supply of a plurality of reference mark controls, its wiring is different, and will realize that from practical situations the break-make of the power supply of reference mark control more than two will be complicated and uneconomic; 3), the common power switch is considered from the angle that conveniently connects up and be easy to discern, it generally is placed on controlled electric accessories, have if desired a reference mark come all power supplys of centralized control so wire structures will be very numerous and diverse, and the position at this reference mark can't arbitrarily change.
Summary of the invention
The utility model mainly provides a kind of ac power switch that has all functions of common power switch and do not change the Long-distance Control of original electric wiring structure.
The technical scheme that its technical matters that solves the utility model adopts.The ac power switch of this Long-distance Control, comprise signal projector and power-supply controller of electric, power-supply controller of electric is installed in the terminal box, which is provided with one is used to receive from the control signal of signal projector and the signal receiving device of break-make power supply, power-supply controller of electric is serially connected on a live wire or the zero line, and live wire and zero line do not need together in the thereto; Also be provided with the manual switchgroup that is used for the break-make power supply on the power-supply controller of electric; Also be provided with the required direct supply of signal receiving device operate as normal on the power-supply controller of electric,, can both power to signal receiving device no matter this direct supply is being switched on or switched off state by the AC power of power controller controls.
The technical scheme that its technical matters that solves the utility model adopts can also be further perfect.Described manual switchgroup is: a kind of is the output terminal of the lead access signal receiving device of hand switch, controls switching on or off of power supply by the output state that changes signal receiving device.Another kind is that hand switch directly is connected in series mutually with power lead.Described signal projector comprises coding circuit and radiating circuit; Signal receiving device comprises signal amplification circuit and decoding scheme, and decoding scheme is connected with device such as the controllable silicon or the relay etc. of control on/off.A signal projector can be controlled a plurality of power-supply controller of electric respectively, and each power-supply controller of electric can be controlled by a plurality of signal projectors.A signal projector can send different signals, controls a plurality of different power-supply controller of electric; A plurality of signal projectors can send identical signal, control same power-supply controller of electric.Owing to be provided with coding circuit on signal projector, the signal receiving device on the power-supply controller of electric is provided with decoding scheme, and can freely setting as required of coding and decoding scheme sets up power control system flexibly.Described direct supply is: a kind of is that alternating current is after rectification, filtering and get; Second kind is chemical cell; The third is a uninterrupted power source.
1), power-supply controller of electric is serially connected on a live wire or the zero line effect that the utility model is useful is:, live wire and zero line do not need together in the thereto, and the employing structural design identical with the common power switch, guaranteed the interchangeability of it and common power switch.2), manual switchgroup can control the break-make of power supply independently, the operator can be with the break-make of the same method control power supply of operation common power switch.3), the operator can realize the break-make of Long-distance Control power supply by signal projector.
