Abstract
The invention discloses a method and a device for fire protection and positioning of a double power source switching device. The technic scheme of the invention is that: signal detection and logic processing are combined and solved in a weak electrical loop by a photoelectric scheme to increase the reliability and electromagnetic compatibility of the double power source switching device.
Description
Technical field
The invention belongs to the low-voltage electrical apparatus field, relate to double-power supply switching device, particularly relate to a kind of double-power supply switching device that can be used for fire-fighting system.
Background technology
In order to improve the electricity quality of using of power supply grid, when power supply broke down, double-power supply switching device can switch to current supply circuit with another road stand-by power supply, to guarantee the operate as normal of electrical appliance.General double-power supply switching device is made up of two circuit breakers, electronic and manual-operating mechanism, position probing master switch, controller.Double-power supply switching device switches on and off separately the power supply that connects, electronic or manual-operating mechanism is used for operating the mechanical action of described circuit breaker, the position that the position probing master switch detects circuit breaker for controller provides position signalling, controller the motor of operating mechanism is sent work order respectively by two circuit breakers.
For fire-fighting system, need cut off two road power supplys simultaneously, at this moment the position of two circuit breaker handles all is in the centre position of the electric operation of " branch " and " closing ", traditional way is to realize with the sensitive switch in forceful electric power loop, because each circuit breaker handle carries out all needing to pass through the fire-fighting position location in the process of electric operation of " branchs " and " closing ", therefore the electrical action of fire-fighting location need shield at ordinary times, but the mechanical action of sensitive switch is inevitable.In reliability relatively poor and when action, produce strong electric spark and cause the Electro Magnetic Compatibility of whole double-power supply switching device relatively poor, the fire-fighting poor performance.
In addition, little disconnected type duplicate supply is applied in the distribution of fire-fighting equipment widely, if will realize that fire-fighting control all is to add the shunt opening servicing unit on little disconnected limit usually, the contact between duplicate supply cut-out load and power supply can be controlled in the feasible control center that disappears.This quadrat method has increased the peripheral wiring of duplicate supply, makes the forceful electric power secondary line become complicated, and reliability reduces, and cost increases by 140 yuan.
Summary of the invention
Technical problem of the present invention is: the electronics localization method that proposes a kind of double-power supply switching device, input, logical process are joined together, solve reliability and the Electro Magnetic Compatibility that improves double-power supply switching device in weak electrical loop, satisfy the requirement of fire-fighting.
Technical scheme of the present invention is: two escapements folders about being used for operating the action of described breaker mechanical on the double-power supply switching device operating mechanism and having, described two escapements press from both sides the electric operation that the circuit breaker handle separately of clamping respectively carries out " branch " and " closing ", connect and the branch deenergizing; What be used for driving the escapement folder is a fan-shaped cam, on the fan-shaped circular arc of cam, increase the logical breach of a light through hole or light, when circuit breaker handle during, a photoelectric interrupter is installed at the light through hole or the logical breach of light of cam at " branch " and " closing " position middle; When the position of cam rotation time through hole arrives photoelectric interrupter, light during by the light through hole photoelectric interrupter just export the position signalling that a signal of telecommunication comes to provide for controller circuit breaker.Controller sends the instruction that quits work to the motor of operating mechanism, and position probing is realized by electronic unit like this, has finished goal of the invention, has solved technical problem of the present invention substantially.
Can be improved to according to one embodiment of the invention technical scheme of the present invention: light through hole or light at cam lead to the centre of breach at the fan-shaped circular arc of cam.Manufacturability when installing and debug has all had raising like this.
According to one embodiment of the invention, technical scheme of the present invention can further be improved to: light through hole or the logical breach of light at cam are two or more, or even a string light through hole that is positioned on the camber line.In the cam running, produce a series of light pulses like this, be easy to determine the fire-fighting position signalling of circuit breaker certainly.The beyond thought effect of another of this scheme is the speed that can read handle motion, thereby detect the running status of motor and operating mechanism, the fault that can judge motor and operating mechanism for controller provides possibility, and solution can be in mechanism be provided during early stage and job failure.Obviously this beyond thought effect is significant in fire-fighting system, and particularly when motor power was undesirable, motor can be judged for fire protection control center provides precise parameters to carry out fail safe when changeing less than ideal position.
According to one embodiment of the invention, technical scheme of the present invention can further be improved to: cam has an arc grating, grating provides electrical pulse sequence by optical chopper for controller during motion, controller can be judged the movement velocity and the circuit breaker handle position of motor and operating mechanism, thereby controller can further provide performance that accurate control increases substantially double-power supply switching device, derive from the function of accident analysis.
Under the situation that does not break away from invention thought of the present invention, the location swap of optical chopper and light through hole, light breach, light through hole string, grating, the inventor thinks that congenerous replacement then is identical technical scheme based on Sherman Act; Long through-hole, the long through-hole that has grating and long nick are the technical scheme of the situation that does not break away from invention thought of the present invention in addition, all should obtain patent protection.
The invention has the beneficial effects as follows: basic characteristics that adopted this structure of photoelectric scheme are the adjustability extreme differences of mechanical positioning that show as the sensitive switch in original forceful electric power loop.The benefit that adopts photoelectric scheme is that the adjustability of extreme position is fabulous, width-pulse at the light through hole in basic scheme of the present invention just can obtain the location buffering at controller, light through hole in the follow-up improvement project, light through hole string, grating are designed to controller can judge that the fault of motor and operating mechanism provides possibility, and solution can be in mechanism be provided during early stage and job failure.Therefore the present invention reached Patent Law alleged have outstanding substantive distinguishing features and an obvious improvement, and have beyond thought effect.The photoelectric interrupter circuit is simple, and is contactless, the reliability height, and cost is low, and only 1 yuan of multiple spot has economic benefit nearly a hundred times.
