Abstract
The utility model discloses a detachable temporary earthing device, which comprises an earthing lock connected with an earthing flat iron. The earthing lock is connected with a connecting wire through a standard connector, and the connecting wire is connected to a standard access inside a terminal box via the standard connector. The earthing device has reasonable structure, and is capable of not only resolving problems of relatively large cable consumption and maintenance cost caused by utilizing a large number of fixed earthing locks, but also managing earthing lines in an error-prevention manner according to requirements.
Description
Technical field:
The utility model relates to a kind of anti-misoperation locking technique device of temporary ground wire.
Background technology:
Personal safety when guaranteeing to be engaged in the converting equipment service work needs should install earth connection or ground connection disconnecting link to the everyway that may deliver to interruption maintenance equipment, with the personnel that cause that prevent to send a telegram here the suddenly injury accident that gets an electric shock.
But in practice, because the temporary ground wire of installing is forgotten dismounting, the accident that causes the band earth connection to close a floodgate occurs repeatedly in system, brings serious threat to safe operation, therefore managed temporary ground wire, prevented that with the misoperation of earth connection combined floodgate be the foothold of this invention.
According to " transformer station's anti-misoperation technical stipulation " requirement, all temporary ground wires all must be included five anti-management systems in, realize the locking management.Along with the extensive utilization of comprehensive automation system of transformer substation in transformer station, utilize computer supervisory control system, gather the state information of transformer station's various kinds of equipment, by predefined five-defence block logic, all kinds of operations of managing electric substation's switchgear become a kind of accurately method easily.And the anti-error technical management measures of the temporary ground wire of transformer station also realizes based on this type of mode.
To the management of temporary ground wire anti-misoperation locking, current way is to be provided with the dead earth lock at the position that requires to install temporary ground wire, and lockset is inserted the five-defence block system by secondary line or network communication line at present.But there are some problems in practice and in transforming, at first be because the temporary grounding line position that will consider is a lot, the everywhere all will be provided with the dead earth lockset, corresponding laying a large amount of cable and the cable protection pipe of needing, and material requested is locked because of ground connection is installed by electric substation, operating expenses is bigger; In service in addition because dead earth is locked long term exposure out of doors, and spoilage is higher, maintenance workload and expense are bigger.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, both can solve cable consumption and the bigger problem of maintenance cost that a large amount of employing dead earth locks cause, and can carry out the detachable temporary grounding device of anti-misoperation management simultaneously again as requested to earth connection.
Technical solution of the present utility model is:
A kind of detachable temporary grounding device is characterized in that: comprise the ground connection lock that is connected with the ground connection band iron, the ground connection lock is connected with connecting line by standard interface, and connecting line is connected with standard access port in the terminal box by standard interface.
The utility model is rational in infrastructure, both can solve cable consumption and the bigger problem of maintenance cost that a large amount of employing dead earth locks cause, can carry out the anti-misoperation management to earth connection as requested again simultaneously.
Description of drawings:
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is a fundamental diagram of the present utility model.
Embodiment:
A kind of detachable temporary grounding device comprises the ground connection lock 12 that is connected with ground connection band iron 11, and the ground connection lock is connected with connecting line 14 by standard interface 13, and connecting line is connected with standard access port 15 in the terminal box by standard interface.
Circuit working principle of the present utility model is:
When the lockset of need access earth connection meets " five is anti-" rule, press the button AN, 1,2 termination energizes, baffle plate DB is opened in the electromagnet coil action, and keyhole is inserted in the earth connection rotary head, drives travel switch SK displacement (3,4 after putting in place; 7,8 are normal opened contact change normally closed contact, 5,6; 9,10 are normally closed contact change normal opened contact.
