Abstract
The utility model provides a novel loading situation display, which is connected with loading concatenation, comprising a sampling portion and an indicating portion which are connected in parallel. The loading situation display can indicate according to the flowing electrical current, but not the flowing voltage, thereby exactly indicating whether the loading is in a normal working condition or not.
Description
The utility model relates to a kind of industrial instrument that can indicate load conducting situation, particularly a kind of loading condition display.
The instrument of existing indication load conducting situation, having a kind of is that display is connected in parallel in the load, this display is according to whether voltage being arranged in the load rather than whether electric current being arranged by indicating, therefore, it can only be indicated has voltage to add in the load, whether veritably whether have electric current pass through, i.e. operate as normal if can not specify load.Also have a kind of induction by current formula in addition, thereby its is according to the working condition of responding to the indication load by the electric current of load.But if there is stronger magnetic field around display, this display is more difficult operate as normal just, and electric current has less variation, and indication brightness has bigger variation, and therefore, its versatility is poor, particularly can not indicate DC load.
The purpose of this utility model is to provide a kind of novel loading condition display, and this loading condition display can indicate whether operate as normal of load truly.
The purpose of this utility model is achieved in that a kind of loading condition display, and this loading condition display and load are connected in series, and this loading condition display includes sampling part and indicating section in parallel at least.
The sampling part of described loading condition display is one group of diode group or two groups of diode connected in parallel groups that conducting direction is opposite, and every group has two diodes of conducting in the same way at least; Described indicating section is diode in series and light emitting diode.
The sampling part of described loading condition display is one group of diode group or two groups of diode connected in parallel groups that conducting direction is opposite, and every group comprises two diodes of conducting in the same way at least; Described indicating section is the resistance and the light emitting diode of series connection.
The sampling part of described loading condition display is a sample resistance, light emitting diode or the neon lamp of described indicating section for boosting and connect by coil.
The sampling part of described loading condition display is two diodes, light emitting diode or the neon lamp of described indicating section for boosting and connect by coil.
The sampling part of described loading condition display is two groups of diode connected in parallel groups that conducting direction is opposite, and every group comprises two diodes of conducting in the same way at least; Described indicating section is the light emitting diode that connects by electric bridge.This electric bridge is provided with two groups of diode groups of conducting in the same way in parallel, and this diode group is connected in series in the same way with light emitting diode, and every group is provided with two diodes, and the centre of two diodes in every group is connected across the two ends of sampling part respectively.Further, described light emitting diode also is in series with a resistance.
Whether use loading condition display of the present utility model, can indicate has electric current to pass through in the load, can indicate whether operate as normal of load truly; And be not subjected to the interference of external magnetic field, all can indicate highly versatile to the alternating current-direct current load.This loading condition display also has reliable accurate, simple, easy to make, the low cost and other advantages of circuit of indication.
