Abstract
The invention discloses a construction method of a solar energy lightning protection facility on a building roof. The construction method comprises steps of carrying out external lightning protection and equipotential bonding on a solar energy photovoltaic power system, shielding and protecting a power circuit of the solar energy photovoltaic power system. The solar energy lightning protection facility has the characteristics of good lightning stroke resistant effect, wide application range and universality; the construction method is a fundamental measure for guaranteeing the personal safety and property safety of building users and is an optimal means for the lightning stroke anticipating control of the solar energy facility; therefore, the construction method has the practical applicability characteristic; and the construction method has the systematic characteristic as the anticipating control is comprehensively carried out in terms of external lightning stroke anticipating control, equipotential bonding, circuit shielding, power line and signal wire protection of the solar energy facility.
Description
Technical field
The present invention relates to a kind of building roof solar energy lightning protection facility job practices.
Background technology
In recent years, the building roof solar power-generating facility is more and more, and effect is obvious, carries out emphasis as green energy resource and applies.But because in the solar water heating system, be provided with storage tank, support, heating, vacuum pipe and upper and lower conduit, and the intellectuality of solar product height, auxiliary heating, water level, water temperature show automatically, moisturizing, the automatically control of cutting off the water supply, and these functions all realize by electronic installations such as special purpose computer control chip, sensing devices.Electronic installation is indoor; Auxiliary heating, sensing device are outdoor, in the solar water heater case.The holding wire of the power line of these electronic installation power supplies, demonstration and control usefulness, control line also can suffer the impact of indirect lightning strike and LEMP except directly being struck by lightning.In recent years, the frequency that the building roof solar power-generating facility is struck by lightning is very high, brings threat for people's life security, brings loss for people's property.
Summary of the invention
The object of the present invention is to provide a kind of anti-lightning strike effective building roof solar energy lightning protection facility job practices.
Technical solution of the present invention is:
A kind of building roof solar energy lightning protection facility job practices is characterized in that: comprise the following steps:
1) solar energy is estimated the outside lightning protection of electricity generation system: installing the lightning rod that exceeds solar panel additional from 3 meters distant places of solar water heater cell panel, and carrying out ground connection;
2) the solar photovoltaic generation system equipotential connects: solar water heater metallic support, hardware are connected as equipotential with lightening protection installation on the building;
3) shielding of solar photovoltaic generation system power circuit: carry out the shielding of outdoor various power circuits, and carry out equipotential with other hardwares and be connected;
4) protection of solar photovoltaic generation system power line, the two-stage protection is set, first order protection: first order arrester is arranged in parallel between solar panel and inverter, carry out the lightning current discharge, the residual voltage of lightning surge at this section circuit is controlled in 4000 volts first order arrester model: AT PORT/4P-B100 three-phase B level power supply arrester; Second level protection: between inverter and the power distribution cabinet and between power distribution cabinet and the load equipment; the selected module design; change easily surge protection device, the lightning surge residual voltage is controlled in 2500 volts, second level arrester model: AT T385/4P-C40 three-phase C level power supply lightning arrester box.
The concrete grammar of step 3) is: solar water heater all will adopt shielding line from roof to the power circuit that uses the hot water room, shielding line passes the shielded metal pipe again, the metal tube upper end is connected with rack of solar water heater, and the metal tube lower end is connected to connect with roof strap type lightening protector.
The present invention is anti-lightning strike effective, and range of application is large, has the universal characteristics; The enforcement of this engineering method is to be the personal safety that ensures the building user and the fundamental measure of property safety, is the best means of building roof solar power-generating facility thunderbolt pre-control, therefore has the practicality characteristics; This engineering method has been carried out pre-control, so have systemic characteristics from outside thunderbolt pre-control, equipotential connection, circuit shielding, power line, the holding wire protection of solar power-generating facility comprehensively.
The invention will be further described below in conjunction with embodiment.
The specific embodiment
A kind of building roof solar energy lightning protection facility job practices comprises the following steps:
