Abstract
The invention relates to the technical field of electrical protection and discloses an arc light protecting device based on UVC sensors. The arc light protecting device based on the UVC sensors comprises a detecting unit and a main control unit, wherein the detecting unit comprises a plurality of deep ultraviolet sensors and a sensor concentrator, the deep ultraviolet sensors are installed at malfunction detecting points of a switch cabinet or other electrical devices respectively and connected to the sensor concentrator through cables, the sensor concentrator is connected with the main control unit through a cable, an integrated current over-current signal is logically operated and output as a trip signal after the main control unit receives a signal from the sensor concentrator, a power supply of a malfunction device is cut off, and the detecting unit can be one or more sets which are connected to different electrical devices respectively. The deep ultraviolet sensors which are used for detecting UVC components (ultraviolet light with the wave lengths from 200nm to 280nm) in arc light are adopted, and therefore the arc light protecting device based on the UVC sensors is very strong in anti-interference performance and reliability and high in flexibility.
Description
Technical field
The invention belongs to the electic protection technical field, relate in particular to a kind of arclight protective device based on the UVC transducer.
Background technology
The arclight resist technology is a kind of electric equipment and force device error protection technology of novelty.Because electric fault when taking place in electric equipment and force device; general all with the generation of arclight; so the error protection of carrying out electric equipment and force device by the detection of arclight have simple directly, advantages such as reliable in action, quick action, thereby have widely in electric power system, foreign-going ship, electric railway etc. and to use.
Present existing arclight resist technology, detection all be visible light part in the arclight.But because the existence of surround lighting; the detection of arclight must arrange a very high threshold values to avoid protecting misoperation; need very strong arclight could trigger the action of arc protection; could guarantee the reliability of arc protection action; but but can't guarantee the sensitivity of arclight protective device, can't carry out error protection to electric equipment and force device effectively.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of good reliability, highly sensitive arclight protective device.
Complete skill scheme of the present invention is: a kind of arclight protective device based on the UVC transducer comprises: probe unit and main control unit.
Described probe unit comprises some deep UV (ultraviolet light) transducers and sensor concentrator.
Described deep UV (ultraviolet light) transducer is installed in the fault-finding point place of switch cubicle or other electric equipments, is connected on the sensor concentrator by cable.
Described sensor concentrator is connected with main control unit by cable.
Described main control unit is after receiving the signal of sensor concentrator, and comprehensive overcurrent signal is exported trip signal, the power supply of disengagement failure equipment through after the logical operation.
Described probe unit can be one group or connect many groups of different electric equipments respectively.
The present invention compared with prior art has following beneficial effect:
The invention provides a kind of arclight protective device based on the UVC transducer; adopt the deep UV (ultraviolet light) transducer that detects the UVC composition (ultraviolet lights of wavelength 200 ~ 280 nanometers) in the arclight; and there is not the UVC composition under the normal condition in the atmosphere; thereby traditional relatively arclight protective device; the present invention has very powerful interference free performance, is the situation that false triggering can not take place for sunlight, photoflash lamp or high light torch.Because deep UV (ultraviolet light) transducer of the present invention is insensitive to surround lighting; when guaranteeing reliability, it is very high that sensitivity of the present invention can design, and can accurately detect faint electrical discharge arc; implement the protection action timely, avoided the extensive damage of electric equipment.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, does not constitute to improper restriction of the present invention, in the accompanying drawings:
Fig. 1 is structural representation of the present invention.
Embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Present embodiment provides a kind of arclight protective device based on the UVC transducer, and structure comprises probe unit and main control unit 1 as shown in Figure 1; Described probe unit comprises sensor concentrator 2 and 3 deep UV (ultraviolet light) transducers 3; Described deep UV (ultraviolet light) transducer 3 is installed in the fault-finding point place of electric equipment 4, is connected on the sensor concentrator 2 by cable.
Described sensor concentrator 2 is connected with main control unit 1 by cable.
Described main control unit 1 is behind the signal that receives sensor concentrator 2, and comprehensive overcurrent signal is exported trip signal through after the logical operation, cuts off the power supply of out of order electric equipment 4.
The present invention adopts the deep UV (ultraviolet light) transducer 3 that detects the UVC composition (ultraviolet lights of wavelength 200 ~ 280 nanometers) in the arclight; and there is not the UVC composition under the normal condition in the atmosphere; thereby traditional relatively arclight protective device; the present invention has very powerful interference free performance, is the situation that false triggering can not take place for sunlight, photoflash lamp or high light torch.Because 3 pairs of surround lightings of deep UV (ultraviolet light) transducer of the present invention are insensitive; when guaranteeing reliability, it is very high that sensitivity of the present invention can design, and can accurately detect faint electrical discharge arc; implement the protection action timely, avoided the extensive damage of electric equipment.
More than technical scheme that the embodiment of the invention is provided be described in detail, used specific case herein principle and the execution mode of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
