Description
Technical field
The present invention relates to transformer technology fields, are a kind of standby electricities with break prompt in isolated island protection particularly
Pond inverter.
Background technique
Since photovoltaic DC-to-AC converter is a most important ring in photovoltaic system, under the long-term exposing to the weather of photovoltaic system, need
Overhauling to photovoltaic DC-to-AC converter for service personnel's not timing is wanted, and photovoltaic DC-to-AC converter is divided into separate inverter unit, gird-connected inverter
With reserve battery inverter；
Wherein reserve battery inverter needs to power off electric network source in maintenance, but since reserve battery inverter is
A kind of special inverter, it can provide exchange and supply electricity to specified load, and when the loss of power accident occurs in power grid, reserve battery is inverse
Become device power generation and locally loaded with power grid low-pressure side, if just emergent power matches, is easy to appear self-centered maintenance
Generating state, to " isolated island " phenomenon occur, it is therefore desirable to it adds isolated island and protects function, but environment outdoors more than photovoltaic system
Lower setting, since outdoor uncertainty is more, the function be easy it is directly or indirectly unexpected impaired, service personnel can not be straight
In the case that sight is learnt, inverter is caused to shut down fault, there are still electric currents will injure inspection for the inverter of Awaiting Overhaul at this time
Repair the personal safety of personnel.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of reserve battery inverter with break prompt in isolated island protection.
To achieve the goals above, the present invention is to realize by the following technical solutions: a kind of band in isolated island protection
The reserve battery inverter of break prompt, structure include input interface, connecting terminal, body, the input interface and wiring
Terminal is installed on body the same side, and the inside of the body includes hot prompt part, controller, inverter bridge, radiator, the heat
Property prompt part be mounted on the inner wall of body and matched with radiator, the signal end of the controller and the company of input interface
It connects, wherein controller and inverter bridge, radiator are electrically connected, and driving end is equipped in the radiator, and the hot prompt part is set
There are hot body, sound film, sounding body, the hot body is circular configuration, and sounding body, the sounding body and sound are equipped on its periphery
Film matches.
As a further improvement of the present invention, the sound film is embedded in the two sides of hot body.
As a further improvement of the present invention, the sounding body is equipped with several solid steel blocks.
As a further improvement of the present invention, the inside of the sound film include positive magnet, strut, sickle-shaped movable plate,
Idler wheel, cathode magnet, the anode magnet attract each other with cathode magnet, and the cathode magnet is located at the tip of sickle-shaped movable plate

2, the present invention fixes sickle-shaped movable plate using the adsorption capacity of positive magnet and cathode magnet, when the electric current of internal body
It is reduced to zero (when namely body is in shutdown status), radiator does not work, but since internal component of machine is not
Its internal heat still has when running, and radiator at this time does not work and just can not adequately disperse heat, to make
The temperature for obtaining internal body is higher, the loss of excitation of positive magnet Yu cathode magnet is made with this, sickle-shaped movable plate is counterclockwise along warm
Property body whirlpool down contacted with each solid steel block to issue rub-a-dub rub-a-dub the sound, thus prompt service personnel's body in shut down
State and internal electric current is not present, it is ensured that the personal safety of service personnel.
3, solid steel block of the present invention is due to using steel material, in the case where the rotation of sickle-shaped movable plate taps will not with it is negative
Adsorption reaction occurs for pole magnet, meanwhile, solid steel block acts on simultaneously with sound film, it is ensured that the more loud sounding of knock, i.e.,
Make also can clearly prompt service personnel under environment noisy outdoors.
4, the sickle-shaped movable plate of the present invention cooperates jointly with reciprocal resilient structures, utilizes circumsphere and strut fixed reset spring
A fulcrum, and another fulcrum of reset spring, when sickle-shaped movable plate occurs mobile, is inside received together by interior connection of receiving
To pressed home spring, therefore, sickle-shaped movable plate under the reciprocal elastic force of reset spring, it can be achieved that the stroking prompting of duration,
Avoid of short duration prompt that from can not maximizing prompt to service personnel.
