Abstract
The utility model relates to an explosion-proof distribution control box comprising an explosion-proof distribution control box body, wherein a control box panel (1) is arranged at the right side of the explosion-proof distribution control box body; and a digital display instrument (2) is arranged in the explosion-proof distribution control box body. The explosion-proof distribution control box is characterized in that the control box panel (1) is provided with a glass window (3); the position for mounting the digital display instrument (2) is corresponding to the position for the glass window (3); and a magnetic induction sensor is arranged in the digital display instrument (2). For the explosion-proof distribution control box, the magnetic induction sensor is arranged in the digital display instrument, thus being able to realize the aim for adjusting the parameters by opening the box cover without interruption of power supply; as the magnetic induction sensor is short in response time and is sensitive in response, a magnetic rod can be used to be close to the special part of the digital display instrument outside the glass window, thus being able to simulate the key at a thin-film switch part; and the the explosion-proof distribution control box has no defect in aging of a spring and has long service life.
Description
Technical field
The utility model relates to a kind of explosion-proof power distribution control cabinet, belongs to the electrical equipment control field.
Background technology
The explosion-proof power distribution control cabinet that use in the explosive atmospheres such as factory zone, the lid of unpacking need to cut off the power supply when in the inner electrical equipment of maintenance explosion-proof power distribution control cabinet or adjustment digital display control instrument parameter, carry out the instrument face plate operation, problem is that digital display control instrument also can cut off the power supply if cut off the power supply the lid of unpacking.
Conventional constantly establish case lid by cable to adjust parameter be to take perforate on the panel of explosion-proof power distribution control cabinet, carry out Manual pressure bar and spring reset with the thin film switch position of the action bars aligning digital display control instrument of mechanical thimble and so on.(excesssive gap does not reach requirement because the explosion suppresion surface difficulty of processing between the panel of explosion-proof power distribution control cabinet and the operation push rod is large, it is large that the damping of the too small push rod operational stroke in gap becomes), and spring is fatigue aging in time, can bring difficulty to resetting of push rod, so that traditional explosion-proof power distribution control cabinet is lower useful life.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of explosion-proof area constantly establish by cable case lid adjust parameter and useful life higher explosion-proof power distribution control cabinet.
The purpose of this utility model is achieved in that
A kind of explosion-proof power distribution control cabinet, it comprises explosion-proof power distribution control cabinet body, the front of described explosion-proof power distribution control cabinet body is provided with the control cabinet panel, described explosion-proof power distribution control cabinet body interior is provided with digital displaying meter, offer glass vision panel on the described control cabinet panel, the installation site of described digital displaying meter is positioned at the position correspondence of glass vision panel, and described digital displaying meter inside is provided with magnetic induction sensor.
Magnetic induction sensor is the potted element that comprises Hall switch, voltage differential amplifier, level trigger and collector electrode output.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can realize constantly establishing by cable the purpose that case lid is adjusted parameter because digital displaying meter inside is provided with magnetic induction sensor.Because the magnetic induction sensor response time is short, be quick on the draw, can be close with the digital displaying meter privileged site of bar magnet glass vision panel outside, just can simulate at thin film switch position button, the defective that does not exist spring to wear out, useful life is longer.
Description of drawings
Fig. 1 is the structural representation of the utility model explosion-proof power distribution control cabinet.
Wherein:
Face is provided with control cabinet panel 1
Embodiment
Referring to Fig. 1, a kind of explosion-proof power distribution control cabinet that the utility model relates to, it comprises explosion-proof power distribution control cabinet body, the front of described explosion-proof power distribution control cabinet body is provided with control cabinet panel 1, described explosion-proof power distribution control cabinet body interior is provided with digital displaying meter 2, offer glass vision panel 3 on the described control cabinet panel 1, the installation site of described digital displaying meter 2 is positioned at the position correspondence of glass vision panel 3, described digital displaying meter 2 inside are provided with magnetic induction sensor, and described magnetic induction sensor is for comprising Hall switch, the voltage differential amplifier, the potted element of level trigger and collector electrode output.
Operation principle: explosion-proof power distribution control cabinet, the panel film switch original function that has kept the inner digital displaying meter of explosion-proof power distribution control cabinet, be provided with magnetic induction sensor in digital displaying meter inside in addition, use one to save bar magnet that permanent magnet makes or special neodymium iron boron penholder (magnetizing) across glass vision panel during near the digital displaying meter corresponding site during operation, utilize Hall effect that the close variable signal in magnetic field is converted to the signal of telecommunication, change by level, trigger, reach and press switch key---conducting, discharge switch key---effect that not conducting is same.
Claims (2)
