Technical field
The utility model belongs to the earthing device technical field of intermediate switchgear cabinet, particularly a kind of warning inductive grounding line for intermediate switchgear cabinet.
Background technology
In the network system of 10-35kV, because power system operating mode changes, 10-35kV intermediate switchgear cabinet often needs the operation carrying out bus grounding disconnecting link reliable ground.And when operating; often can there is insensitive, the even situation such as bite in the bus grounding disconnecting link of intermediate switchgear cabinet; once there is this situation, often because of the restriction of intermediate switchgear cabinet self electric locking device, directly affect the change of other equipment running status.
In real work, whether staff can confirm the integrity of grounding switch in intermediate switchgear cabinet usually according to the ground signalling of intermediate switchgear cabinet and guidance panel signal, or intact to judge the contact of grounding switch in intermediate switchgear cabinet by position after the conjunction visually observing grounding switch; These two kinds of modes above-mentioned all well cannot detect the security requirement of grounding switch reliable contacts.
Intermediate switchgear cabinet is arranged on a closed office work, connecting outer conductor takes cable to connect, after intermediate switchgear cabinet is stopped transport, because wall and partition cannot confirm whether the cable other end has electricity, reliably can not distinguish that whether the ground connection occurring cable is reliable, only confirm that in intermediate switchgear cabinet, grounding switch operation puts in place simultaneously, uncertain single-phase or three contact good, or two-phase closes a phase, and the situation such as not close all cannot confirm, cause staff cannot judge the integrity of ground connection at work, this method of operation, violate electric power safety countermeasure, increase the security risk of operating personnel.
Utility model content
The purpose of this utility model is to provide a kind of warning inductive grounding line for intermediate switchgear cabinet, this ground line configuration is simple, easy to operate, the fail safe that workmen operates at work can be met, the integrity of the inner disconnecting link contact of intermediate switchgear cabinet and breakpoint can be verified in security protection measure, the security reliability of isolation personnel and equipment can be played, meet the requirement of insulation and mechanical performance, and can operate outward at intermediate switchgear cabinet, away from the charged position such as sealing chamber at intermediate switchgear cabinet rear portion, greatly reduce the security risk of personnel and equipment.
For reaching above-mentioned technical purpose, the utility model adopts following technical scheme to be achieved.
A kind of warning inductive grounding line for intermediate switchgear cabinet, described intermediate switchgear cabinet is provided with A, B, C three-phase, described A, B, C three-phase is electrically connected with grounding switch respectively, one end ground connection respectively of described grounding switch, it is characterized in that, described warning inductive grounding line comprises insulation crust, the side of described insulation crust is provided with three and measures binding post, the opposite side of described insulation crust is provided with three ground connection binding posts, three power supplys are provided with in described insulation crust, the negative pole correspondence of each power supply is by described ground connection binding post ground connection, the positive pole of each power supply is electrically connected with an indicator light, corresponding three earth terminals being electrically connected to intermediate switchgear cabinet by measuring binding post of described indicator light.
Feature and further improvement of the technical program are:
Described indicator light adopts LED.
The indicator light be electrically connected with the A of described intermediate switchgear cabinet is red, and the indicator light be electrically connected with the B of described intermediate switchgear cabinet is yellow, and the indicator light be electrically connected with the C of described intermediate switchgear cabinet is blue.
The head of described indicator light gives prominence to insulation crust.
Warning inductive grounding line for intermediate switchgear cabinet of the present utility model, if all ground connection is good for A, B, C three-phase of intermediate switchgear cabinet, three indicator lights are all lit, and prompting staff can safety operation; The imperfect earth of that phase, the indicator light be electrically connected with this can not be lit, and staff checks circuit, repair intact after can safety operation; This earth connection is provided with earth terminal, to intermediate switchgear cabinet secondary ground connection, avoids the misoperation of staff; This earth connection is the imperfect earth of that phase directly to staff's prompting by the color of indicator light.This structure is simple, easy to operate, the fail safe that workmen operates at work can be met, the integrity of the inner disconnecting link contact of intermediate switchgear cabinet and breakpoint can be verified in security protection measure, the security reliability of isolation personnel and equipment can be played, meet the requirement of insulation and mechanical performance, and can operate outward at intermediate switchgear cabinet, away from the charged position such as sealing chamber at intermediate switchgear cabinet rear portion, greatly reduce the security risk of personnel and equipment.
