Abstract
The present utility model relates to a power supply switching device, especially to a stand-by power supply automatic switching device applied to a traffic indicating light which is provided with a solar energy current collection system. The device is composed of an AC contactor which is provided with a coil K1 and a normally closed contact K2, the coil K1 is connected with an AC power supply VCC, and the normally closed contact K2 is connected with a solar energy power supply system SUN. The solar energy lamp stand-by power supply automatic switching device is reasonable in design and simple in structure, the AC contactor is arranged on a light fixture which is provided with the solar energy current collection system, and the power supply mode can be automatically switched by utilizing the electromagnetic principle. Moreover, the energy can be saved, the normal traffic order will not be influenced by the power failure, and lives of people are facilitated to a large extent.
Description
Technical field
The utility model relates to a kind of power transfer device, particularly a kind of stand-by power supply automatic switching control equipment that applies to install the stop-light of solar power current collection system.
Background technology
The traffic lights that municipal administration at present adopts adopts mains-supplied mostly; But there is such problem in actual use; Be that in a single day civil power has a power failure or break down; Stop-light is not indicated or is exactly to adopt the mode of manual switching power supply to supply power, and this control mode is with wasting time and energy, and it is unreliable to control.
Summary of the invention
The purpose of the utility model is to above-mentioned weak point a kind of Solar lamp stand-by power supply automatic switching control equipment to be provided, and on the light fixture that the solar power current collection system is installed, A.C. contactor is installed, and utilizes electromagnetic principle, the automatic switchover powering mode.
A kind of Solar lamp stand-by power supply automatic switching control equipment takes following technical scheme to realize: a kind of Solar lamp stand-by power supply automatic switching control equipment has A.C. contactor; A.C. contactor has coil K1 and normally-closed contact K2; Coil K1 links to each other with AC power VCC, and normally-closed contact K2 links to each other with solar electric power supply system SUN.
Described A.C. contactor adopts CJ12-100A type A.C. contactor.
Operation principle: under the normal power supply situation, the coil K1 of A.C. contactor gets electric, and its normally-closed contact K2 opens, and has broken off solar electric power supply system SUN, and this moment, lamp adopted mains-supplied; When occur to have a power failure or the situation of any burst outage under, coil K1 dead electricity, its normally-closed contact K2 closure that resets is connected solar electric power supply system SUN, sun-generated electric power is supplied power to lamp.When the city power recovery just often, ac contactor coil K1 gets electric, normally-closed contact K2 breaks off, lamp is used mains-supplied again.
A kind of Solar lamp stand-by power supply of the utility model automatic switching control equipment, reasonable in design, simple in structure, on the light fixture that the solar power current collection system is installed, A.C. contactor is installed, utilize electromagnetic principle, the automatic switchover powering mode.Can energy savings, and can not make things convenient for people's life to a great extent because of power failure influences normal traffic order.
Description of drawings
Below will combine accompanying drawing that the utility model is described further:
Fig. 1 is the electrical schematic diagram of the utility model.
Embodiment
With reference to accompanying drawing 1, a kind of Solar lamp stand-by power supply of the utility model automatic switching control equipment has A.C. contactor, and A.C. contactor has coil K1 and normally-closed contact K2, and coil K1 links to each other with AC power VCC, and normally-closed contact K2 links to each other with solar electric power supply system SUN.
Described A.C. contactor adopts CJ12-100A type A.C. contactor.
Under the normal power supply situation, the coil K1 of A.C. contactor gets electric, and its normally-closed contact K2 opens, and has broken off solar electric power supply system SUN, and this moment, lamp adopted mains-supplied; When occur to have a power failure or the situation of any burst outage under, coil K1 dead electricity, its normally-closed contact K2 closure that resets is connected solar electric power supply system SUN, sun-generated electric power is supplied power to lamp.When the city power recovery just often, ac contactor coil K1 gets electric, normally-closed contact K2 breaks off, lamp is used mains-supplied again.
