Description
Technical Field
The utility model relates to the field of electricity, in particular to a ground fault query module.
Background
Currently, a PLC (programmable logic controller) is commonly used for controlling industrial equipment. PLC control requires the use of more switches, modules, sensors, etc. Once the switches, the modules and the sensors are grounded, the PLC cannot acquire correct information or can not work normally, and more troubles are brought to industrial control. At the same time, the staff needs to check one by one, which takes much time.

a ground fault query module, comprising: the device comprises a working module, a working indicator lamp, a fault indicator lamp, a first photoelectric coupler, a second photoelectric coupler, an electronic fuse and an outer shell;
the front of the outer shell is provided with a work indicator lamp and a fault indicator lamp, the work indicator lamp and the fault indicator lamp are electrically connected with the work module, and the work indicator lamp and the fault indicator lamp occupy two input data bits and are used for displaying the state of the electronic fuse;
the working module is positioned at the top position in the outer shell and used for skipping the INTERBUS communication;
the first photoelectric coupler and the second photoelectric coupler are positioned at the middle position in the outer shell;
the first photoelectric coupler is electrically connected with the working module and is used for photoelectric isolation and controlling the electronic fuse to disconnect a subsequent circuit;
the second photoelectric coupler is electrically connected with the working module and is used for photoelectric isolation and feeding back the grounding state of a subsequent circuit of the electronic fuse;
the electronic fuse is positioned at the bottom of the outer shell and is respectively and electrically connected with the first photoelectric coupler and the second photoelectric coupler, and the electronic fuse is used for feeding back the working state and rapidly cutting off the subsequent circuit supply when being grounded.
The utility model has the following beneficial effects:
the utility model can realize rapid checking of the grounded module, reduce a large amount of checking time, accurately inquire the position of the fault module and ensure the stability of industrial control.

Detailed Description
Preferred embodiments of the present utility model will be described in detail with reference to the accompanying drawings so that those having ordinary skill in the art to which the utility model pertains will readily implement the embodiments. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In addition, for the purpose of more clearly describing the present utility model, parts not connected to the present utility model will be omitted from the drawings.
A ground fault query module, comprising: the device comprises a working module 1, a working indicator lamp 2, a fault indicator lamp 3, a first photoelectric coupler 4, a second photoelectric coupler 5, an electronic fuse 6 and an outer shell;
the ground fault query module is arranged in the PLC electrical cabinet and adopts a DIN guide rail installation mode; the ground fault query module is used for creating a segmented circuit in the PLC control main circuit, and no voltage is provided; the ground fault query module occupies an interface address in the PLC control main circuit, and when the PLC control main circuit is used, the address of the ground fault query module is skipped on the PCB, so that the ground fault query module can be inserted between any other modules, and the address of the ground fault query module cannot be identified;
as shown in fig. 1, the front surface of the outer casing is provided with a work indicator lamp 2 and a fault indicator lamp 3, the work indicator lamp 2 and the fault indicator lamp 3 are electrically connected with the work module 1, and the work indicator lamp 2 and the fault indicator lamp 3 occupy two input data bits for displaying the state of the electronic fuse 6;
the working module 1 is positioned at the top position in the outer shell and used for skipping the Internet communication;
the first photoelectric coupler 4 and the second photoelectric coupler 5 are positioned at the middle position in the outer shell;
the first photoelectric coupler 4 is electrically connected with the working module 1 and is used for photoelectric isolation and controlling the electronic fuse 6 to disconnect a subsequent circuit;
the second photoelectric coupler 5 is electrically connected with the working module 1 and is used for photoelectric isolation and feeding back the subsequent circuit grounding state of the electronic fuse 6;
the electronic fuse 6 is located at the bottom position in the outer shell and is electrically connected with the first photoelectric coupler 4 and the second photoelectric coupler 5 respectively, the electronic fuse 6 is used for feeding back the working state, and the subsequent circuit power supply is rapidly cut off when the electronic fuse is grounded.
When the ground fault inquiry is carried out, the ground fault inquiry module is arranged between different modules and is electrically connected with a power interface, and if the work indicator lamp 2 is on and the fault indicator lamp 3 is off, the ground does not exist; if the work indicator lamp 2 is on and the fault indicator lamp 3 is on, there is a ground.
In the description of the present technical solution, it should be specifically noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" as used herein are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the creation of the present utility model can be understood by those of ordinary skill in the art in a specific case.
