The electricity generation systems such as photovoltaic easily are switched off circuit in maintenance, inspection, operation, and interior setting lightning protection, ground connection etc. protect equipment and measure,
When photovoltaic distributed electricity generation system breaks down, it can utmostly reduce the range of power failure.
Current header box, generally only basic functions such as confluence, lightning protection lack data acquisition and monitoring and remote control
Function, under extreme weather situation, especially in the environment of high-temperature high-humidity, to the monitoring of distributed power generation header box with regard to direct
Influence distributed generation system reliability of operation and safety.
Utility model content
In view of the above deficiencies, the utility model provides a kind of distributed power generation header box, realizes to distributed generation system
The automatic open-close lock under extreme weather is realized in the monitoring of temperature and humidity, realizes remote control, protects network system, equipment property
And personnel safety.
In order to achieve the above object, technical solution used by the utility model is as follows: a kind of distributed power generation header box,
Including cabinet, disconnecting link, autoreclose breaker, leakage fire monitoring device, humiture transducer, electric current are installed in cabinet
Mutual inductor, GPRS module, three-phase electric energy meter, remote server；The fire wire output end and autoreclose breaker of the disconnecting link
End of incoming cables be connected, on autoreclose breaker with leakage fire detection device test point, the test point signal access
Collected signal is passed to GPRS module by leakage fire detection device, leakage fire detection device；Humiture transducer will
Collected signal passes to GPRS module；Current transformer is serially connected in the fire wire output end of disconnecting link, current transformer it is defeated
Signal accesses three-phase electric energy meter out, and three-phase electric energy meter is connected with GPRS module；Remote server and GPRS module carry out channel radio
News.
Preferably, the remote server is computer or mobile phone.
Preferably, the autoreclose breaker uses quadrupole autoreclose breaker.
Compared with the existing technology, the beneficial effects of the utility model are as follows: distributed power generation provided by the utility model converges
Flowing case has current transformer, leakage fire monitoring device and humiture transducer, realizes data acquisition monitoring；By warm and humid
Spend stagnation condition setting, it is automatic to send alarm cutting circuit when monitoring temperature reaches 1 boundary's point of maximum temperature, at a temperature of
When being restored to operating temperature, remote server receives to be reminded drop, and long-range control is closed a floodgate, facilitate user in time, accurate grasp distribution
The working condition of formula system had not only guaranteed that it played maximum effect at runtime, but also equipment is prevented to issue in extreme weather state
Raw failure, causes power grid safety accident, protects the safety of equipment safety, the personal safety of maintenance personnel and power grid operation.
Detailed description of the invention
Fig. 1 is electric appliance connection figure inside distributed power generation header box；
In figure, 1 is disconnecting link, and 2 be connecting terminal block, and 3 be autoreclose breaker, and 4 be leakage fire monitoring device, 5
It is current transformer for humiture transducer, 6,7 be GPRS module, and 8 be three-phase electric energy meter.
Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of distributed power generation header box, including cabinet, cabinet is in cuboid, case
It is also equipped with chamber door on body, disconnecting link 1, connecting terminal block 2, autoreclose breaker 3, leakage fire monitoring are installed in cabinet
Device 4, humiture transducer 5, current transformer 6, GPRS module 7, three-phase electric energy meter 8, remote server；The disconnecting link installation
In the intracorporal upper end of case, the fire wire output end of disconnecting link is connected by connecting terminal block 2 with the end of incoming cables of autoreclose breaker,
5 autoreclose breakers in parallel are given in Fig. 1 of the present embodiment, and there is electric leakage on each autoreclose breaker
The test point of fire detection device, the test point signal access leakage fire detection device, and leakage fire detection device will acquire
To signal GPRS module is passed to by connecting terminal block 2；Humiture transducer is mounted on the intracorporal left side of case, uses
GPRS module is passed to by connecting terminal block 2 in the temperature and humidity of acquisition box house, and by temperature and humidity data；Electricity
Current transformer 6 is serially connected in the fire wire output end of disconnecting link, and the output signal of current transformer 6 accesses three-phase electric energy meter, three-phase electricity
Energy table is connected with GPRS module；Remote server is communicated wirelessly with GPRS module.In cabinet the negative terminal of all devices with
Grounding copper bar is connected.
The remote server can be computer or mobile phone.The autoreclose breaker 3 is weighed automatically using quadrupole
Combined floodgate breaker, but not limited to this.
The working principle of the utility model is as follows: the setting tripping critical temperature value first in leakage fire detection device 4；
Humiture transducer temperature acquires the temperature and humidity of box house, and collected temperature and humidity signal is filtered by pressure stabilizing
After the processing of circuit such as wave, operation amplifier, gamma correction, V/I conversion, constant current and reverse protection, it is converted into and temperature and humidity
Linear current signal or voltage signal, and exporting, to monitor acquisition temperature and humidity real time data, and by real time data
It is transferred to GPRS module, GPRS module is faced by wirelessly transferring data to remote server when cabinet temperature and humidity is higher than tripping
When boundary's temperature value, remote server issues alarm signal, sends sub-gate signal to leakage fire detection device 4, makes automatic reclosing
Lock breaker 3 trips, to cut off circuit, safety accident occurs for prevention；When cabinet temperature and humidity drops to tripping critical temperature value
When, remote server sends switching signal to leakage fire detection device 4, and autoreclose breaker 3 is made to close a floodgate.
Using above scheme, the utility model distributed power generation header box realizes monitoring temperature and humidity, and remotely controls
System prevents the safety accident that may occur in advance, substantially increases safety, reliability and the electricity of distributed generation system operation
The safety of net.
