Description
Technical field
The utility model is related to it is a kind of be used for arc light protecting device, especially one kind be swift in response, malfunction can be reduced, can
By the high switch cubicle arc light protecting device of property.
Background technology
Because various short-circuit reasons can cause arc light in switch cubicle, arc light can be broken out with 300m/s speed, because of temperature
It is very high and turn into fire origin.To reduce the harm of arc light to greatest extent, arc light protecting device is designed with switch cubicle.It is existing to open
Closing cabinet arc light protecting device has main control unit（Single-chip microcomputer etc.）, the breaker controlled by main control unit is connected between bus, together
When have sensor for detecting arc light（Pressure sensor or arc photosensor etc.）.Sensor can incite somebody to action in moment caused by arc light
Detection signal delivers to main control unit, controls breaker actuation by main control unit, cutting off the electricity supply makes arc light disappear.Pressure sensor is
For detecting pressure wave（Electrical arcing）, detection signal is sent when detection pressure peak value reaches setting value, typically in electric arc
It can just be detected after 10 ~ 15 milliseconds after appearance；Arc photosensor is to be used to detect another light radiation（Electrical arcing）, detection
Reaction time is swift in response compared to pressure sensor（Only 1 millisecond）, but produced sometimes because of the moment illumination such as flashlight
Malfunction, reliability are low.
The content of the invention
The utility model be in order to solve the above-mentioned technical problem present in prior art, propose one kind be swift in response, can
The high switch cubicle arc light protecting device of reduction malfunction, reliability.
Technical solution of the present utility model is：A kind of switch cubicle arc light protecting device, has main control unit and by master control
The breaker that unit is controlled and is connected between bus, provided with fixed support, is fixed with three interval settings on fixed support
Fibre-optical probe, have optical filter on fibre-optical probe, the fibre-optical probe is connected by optical fiber with main control unit respectively.
The utility model is to install the optical filter for filtering out light beyond wavelength 500nm ~ 550nm additional on fibre-optical probe, can be effective
Exclusive PCR light, breaker is avoided to produce malfunction because of other optical signals；Three optical fiber can be visited by fixed support simultaneously
Head is set at equal intervals with bus, and it is big to monitor coverage rate, the defects of overcoming fibre-optical probe photosurface small, reliably failure is sentenced
It is disconnected, have and be swift in response, malfunction and high reliability can be reduced.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings specific embodiment of the present utility model.As shown in Figure 1：A kind of switch cubicle arc light is protected
Protection unit, there is main control unit 1 and controlled by main control unit 1 and be connected to the breaker 2 between bus, provided with fixed support 3,
Three fibre-optical probes set at equal intervals with three-phase bus 4 are fixed with fixed support 3, have optical filter 5 on fibre-optical probe 4（Protect
Stay wavelength 500nm ~ 550nm arc light）, fibre-optical probe 4 connected by optical fiber 6 with main control unit 1 respectively.During installation, make optical fiber
The optical axis of probe 4 is vertical with bus axis.
