Abstract
The utility model relates to a photovoltaic lightning protection device, comprising a lightning arrester serial set and an alarm unit. The lightning arrester serial set comprises at least three lightning arresters. The lightning arresters at two ends of the lightning arrester serial set are connected with the positive and the negative of a power supply respectively, and any one of other lightning arresters in the lightning arrester serial set is connected with a ground wire. The alarm unit comprises a circuit board, and the circuit board is provided with a plurality of alarm terminals and signal lamps used for sending alarms. The alarm terminals are in one-to-one correspondence with the lightning arresters. The photovoltaic lightning protection device provided by the utility model is high in stability, convenient to install, and convenient to maintain.
Description
Technical field
The utility model belongs to electric field, relates to a kind of lightning protection device, relates in particular to a kind of photovoltaic lightningproof device.
Background technology
Existing photovoltaic lightningproof device, for photovoltaic generating system, is not damaged by lightning overvoltage for the protection of photovoltaic generating system equipment.Photovoltaic lightningproof device is combined by 3 lightning protection devices, and one end has bus-bar to connect, when use, form anodal over the ground, negative pole over the ground, be all 2 structures that lightning protection device is connected between positive pole and negative pole, be commonly called as y-type structure.The remote alarms terminal of photovoltaic lightningproof device is independently to separate.Often complex structure of existing lightning protection device, manufacturing cost is also higher, the most important thing is often to there will be in the middle of the use procedure of plateau the problem puncturing between line.
Utility model content
In order to solve existing technical problem in background technology, the utility model proposes a kind of photovoltaic lightningproof device.
The technical solution of the utility model is: a kind of photovoltaic lightningproof device, and its special character is: comprise lightning arrester series connection group and alarm unit; Above-mentioned lightning arrester series connection group comprises at least 3 lightning arresters; The lightning arrester at the two ends in above-mentioned lightning arrester series connection group is connected with power supply positive and negative electrode respectively, and in lightning arrester group, in other lightning arresters, any one is connected with ground wire;
Above-mentioned alarm unit comprises and on circuit board, circuit board, is provided with some alarm terminals and the signal lamp for reporting to the police; Above-mentioned alarm terminals is corresponding one by one with lightning arrester.
The beneficial effects of the utility model are:
1. stability is high.The utility model changes original one side wiring construction, both sides, upper end respectively connect positive and negative, and the binding post ground connection in the middle of lower end, does like this, insulation distance between the line can improve photovoltaic lightningproof device and use on plateau time, solves breakdown problem between the line of photovoltaic lightningproof device plateau while using.
2. easy for installation.The utility model adopts after integral structure, alarm terminals can be connected at the inner circuit board that adopts of lightning protection device base, exposes alarm terminals and is integrated into one, and raising client uses the simplicity of installation.
3. be convenient to safeguard.After the photovoltaic lightningproof device chip voltage of the every a slice of the utility model improves, middle lightning protection unit is not worked in the time of normal use, is stand-by unit.Because lightning protection device unit is easy disabling unit, the replacement unit after stand-by unit damages as other unit, the maintainability of raising photovoltaic lightningproof system.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein 1-lightning arrester series connection group, 2-alarm unit.
Embodiment
Referring to Fig. 1, the utility model is a kind of photovoltaic lightningproof device, and its special character is: comprise lightning arrester series connection group 1 and alarm unit 2; Lightning arrester series connection group 1 comprises at least 3 lightning arresters; The lightning arrester at the two ends in above-mentioned lightning arrester series connection group 1 is connected with power supply positive and negative electrode respectively, and in lightning arrester series connection group 1, in other lightning arresters, any one is connected with ground wire; Alarm unit 2 comprises and on circuit board, circuit board, is provided with some alarm terminals and the signal lamp for reporting to the police; Alarm terminals is corresponding one by one with lightning arrester.
A kind of photovoltaic lightningproof device of the utility model, photovoltaic lightningproof device inside chip is high voltage high throughflow capacity, without two series connection, just can meet photovoltaic system requirement; The upper and lower two ends of photovoltaic lightningproof device are connected with the earth with both positive and negative polarity respectively; In photovoltaic lightningproof device, between any one binding post, there is very large distance, meet under high conditions and use.
First innovative point of the utility model: the photovoltaic lightningproof device internal chip voltages of every a slice is improved, do not adopt two cascaded structures, adopt single chip architecture can meet photovoltaic system instructions for use.
Second innovative point: change original one side wiring construction, both sides, upper end respectively connect positive and negative, and the binding post ground connection in the middle of lower end, does like this, insulation distance between the line can improve photovoltaic lightningproof device and use on plateau time, solves breakdown problem between the line of photovoltaic lightningproof device plateau while using.
The 3rd innovative point: adopt after integral structure, alarm terminals can be connected at the inner circuit board that adopts of lightning protection device base, expose alarm terminals and be integrated into one, raising client uses the simplicity of installation.
The 4th innovative point: after the photovoltaic lightningproof device chip voltage of every a slice improves, middle lightning protection unit is failure to actuate in the time of normal use.Because lightning protection device unit is easy disabling unit, the replacement unit after stand-by unit damages as other unit, the easy maintainability of raising photovoltaic lightningproof system.
