Description
Technical field
The utility model relates to a kind of protection and failure alarm circuit, is specifically related to the protection and the failure alarm circuit in a kind of solar energy power generating plate loop.
Background technology
In the design of solar energy header box; General both positive and negative polarity at the solar energy tabula rasa respectively adds a fuse (or fuse) and carries out simple overcurrent protection; But whether open circuit in the middle of the connection of this scheme to polylith solar energy tabula rasa; In the solar energy tabula rasa connection procedure whether ground connection is arranged, and the solar energy tabula rasa fault such as refluence of confluxing can't provide protection or alarm indication.Simultaneously, as the insurance of selecting for use is too simple, can not report to the police or show; Check protection loop one by one then; Even the fuse of selecting for use fusing to show also must be through the observation of the unpacking place that just can break down, and fuse is the lossy element; All need after the fault each time to change, make maintenance cost higher.Therefore protected the loop can't protect solar energy tabula rasa loop all sidedly, when producing fault, the efficient of maintenance test is lower in the past, and maintenance cost is higher.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; Provide a kind of and can general protection be provided solar energy tabula rasa loop; Can directly show abort situation and report to the police, and the protection and the failure alarm circuit in lower a kind of tabula rasa of the solar energy cheaply loop of maintenance cost.
The purpose of the utility model is achieved in that
The protection and the failure alarm circuit in a kind of solar energy cheaply of the utility model tabula rasa loop; It is characterized in that: it comprises many group solar energy tabula rasas; Wherein all be in series with little disconnection pass and isolating diode on the loop, place of every group of solar energy tabula rasa; This protection and failure alarm circuit also are provided with signal lamp I and signal lamp II, said signal lamp I with connect after solar energy tabula rasa 1, little disconnection close parallel connection, the signal lamp II is parallelly connected with isolating diode; Perhaps said signal lamp I with connect after the parallel connection of solar energy tabula rasa, isolating diode, the signal lamp II is parallelly connected with little disconnection pass; Perhaps said signal lamp I with connect after the parallel connection of little disconnection pass, isolating diode, the signal lamp II is parallelly connected with the solar energy tabula rasa; Perhaps said signal lamp II with connect after solar energy tabula rasa, little disconnection close parallel connection, the signal lamp I is parallelly connected with isolating diode; Perhaps said signal lamp II with connect after the parallel connection of solar energy tabula rasa, isolating diode, the signal lamp I is parallelly connected with little disconnection pass; Perhaps said signal lamp II with connect after the parallel connection of little disconnection pass, isolating diode, the signal lamp I is parallelly connected with the solar energy tabula rasa.
Have light-emitting diode in said signal lamp I and the signal lamp II.
Said signal lamp I and signal lamp II are the signal lamp of band auxiliary relay.
Compared with prior art, the beneficial effect of the utility model is:
The protection and the failure alarm circuit in a kind of tabula rasa of solar energy cheaply loop have added isolating diode at the positive pole of solar energy tabula rasa; Be used for the positive pole of every group of solar energy tabula rasa is isolated; Conflux again after the isolation; To prevent that the plate earthing of solar energy plate intermediate light from causing that the solar energy electric current flows backwards, increase little disconnection between the positive pole of solar energy tabula rasa and the isolating diode and close, prevent the forward overcurrent.So just, comprehensive protection has been played in each group solar energy tabula rasa loop.
In addition in the parallel connection of the positive and negative end of isolating diode signal lamp; And between the both positive and negative polarity of solar energy tabula rasa the parallel connection band auxiliary relay signal lamp; Thereby can be directly through the observation signal lamp in bright or each signal lamp the contacts status of subsidiary auxiliary relay come failure judgement, and can accurately find the guilty culprit place, and need not OOBA fuse one by one; Maintenance efficiency is higher, and cost is low.
Description of drawings
Fig. 1 is the protection in a kind of solar energy cheaply of the utility model tabula rasa loop and the structural representation of failure alarm circuit.
Wherein: solar energy tabula rasa 1, little disconnection pass 2, isolating diode 3, signal lamp I 4, signal lamp II 5.
Embodiment
Referring to Fig. 1; The utility model relates to the protection and the failure alarm circuit in a kind of tabula rasa of solar energy cheaply loop, comprises many group solar energy tabula rasas 1, wherein all is in series with little disconnection pass 2 and isolating diode 3 on the loop, place of every group of solar energy tabula rasa 1; Wherein the position of solar energy tabula rasa 1, little disconnection pass 2 and isolating diode 3 can be arranged arbitrarily; Said isolating diode 3 is used for the positive pole of every group of solar energy tabula rasa 1 is isolated, and confluxes after the isolation again, flows backwards to prevent solar energy plate 1 intermediate light plate earthing causing solar energy electric current; Said little disconnection closes 2, is used to prevent the forward overcurrent.
The protection in a kind of tabula rasa of solar energy cheaply loop and failure alarm circuit also are provided with signal lamp I 4 and signal lamp II 5.
Said signal lamp I 4 with connect after solar energy tabula rasa 1, little disconnection close 2 parallel connections, signal lamp II 5 is parallelly connected with isolating diode 3; Perhaps said signal lamp I 4 with connect after solar energy tabula rasa 1, isolating diode 3 parallel connections, it is 2 parallelly connected that signal lamp II 5 and little disconnection are closed; Perhaps said signal lamp I 4 with connect after little disconnection close 2, isolating diode 3 parallel connections, signal lamp II 5 is parallelly connected with solar energy tabula rasa 1; Perhaps said signal lamp II 5 with connect after solar energy tabula rasa 1, little disconnection close 2 parallel connections, signal lamp I 4 is parallelly connected with isolating diode 3; Perhaps said signal lamp II 5 with connect after solar energy tabula rasa 1, isolating diode 3 parallel connections, it is 2 parallelly connected that signal lamp I 4 and little disconnection are closed; Perhaps said signal lamp II 5 with connect after little disconnection close 2, isolating diode 3 parallel connections, signal lamp I 4 is parallelly connected with solar energy tabula rasa 1.
