Abstract
The invention discloses a kind of double-deck manhole covers for buried change melt pit entrance security protection, include the electromagnetic lock of upper layer lid, lower layer's lid and integrated electrification display, wherein：The upper layer lid and lower layer's lid are arranged one on the other in the buried top for becoming melt pit entrance；The electromagnetic lock is mounted on lower layer's lid；The electrification of the electromagnetic lock judges signal quoted from the induction coil on the transformer high-voltage cable connector pedestal of the buried change, and the electromagnetic lock provides working power by the step down side of the buried change.The double-deck manhole cover for buried change melt pit entrance security protection of the present invention can directly detect transformer high-voltage cable connector pedestal electrification situation, and easy access personnel make visualization to electrification situation and judge, can intuitively ensure that personnel enter the buried safety for becoming melt pit.
Description
Technical field
The present invention relates to buried change melt pit technical field of safety protection, and in particular to one kind is pacified for buried change melt pit entrance
The double-deck manhole cover of full protection.
Background technology
Covered transformer is usually power transformer, by electrical grid transmission and distributes electric power；The base of Covered transformer
This task is can be by being raised and lowered voltage class between being typically different two or more electrical systems of voltage
Exchange electric energy.During the working life of buried change, various exceptions and fault condition may occur, at this moment staff needs
Timely maintenance and inspection are carried out to transformer, however transformer is high voltage alive equipment, in high-voltage circuitbreaker or high-voltage board band
When electric display failure, service personnel very likely occurs to get an electric shock surprisingly, threatens the person even life security.In addition, electric power
Facility can much be placed on cell, and hole of usually cheating is covered with bright lock, prevent non-service personnel from touching the electric power in transformer
Facility, but since daily maintenance is limited, the bright lock of manhole cover is easy to damage, and transformer room can be caused to be easy to be opened,
Especially transformer normal live line work when, have child or do not know that the people of Covered transformer situation accidentally touches, leave
Some potential safety problems.
Invention content
The purpose of the present invention is overcoming the deficiencies of existing technologies, provide a kind of for buried change melt pit entrance security protection
The double-deck manhole cover, is equipped with electromagnetic lock, can directly detect transformer high-voltage cable connector pedestal electrification situation, easy access people
Member makees visualization to electrification situation and judges, can intuitively ensure that personnel enter the buried safety for becoming melt pit.
Realizing the technical solution of above-mentioned purpose is：A kind of double-deck manhole cover for buried change melt pit entrance security protection,
Electromagnetic lock including upper layer lid, lower layer's lid and integrated electrification display, wherein：
The upper layer lid and lower layer's lid are arranged one on the other in the buried top for becoming melt pit entrance；
The electromagnetic lock is mounted on lower layer's lid；
The electrification of the electromagnetic lock judges signal quoted from the sense on the transformer high-voltage cable connector pedestal of the buried change
Coil, the electromagnetic lock is answered to provide working power by the step down side of the buried change.
The double-deck manhole cover for buried change melt pit entrance security protection of the present invention, advantage and good effect are：
(1) electromagnetic lock is integrated with electrification display, not only there is visualization electrification alarm function before opening electromagnetic lock, but also
Save installation space；
(2) manhole cover is double-layer structure, and lower layer's lid is mounted with that the electromagnetic lock of integrated electrification display, upper layer lid ensure
Melt pit upper sealing plate appearance is smooth, and avoids electromagnetic lock fail in compression；
(3) electrification of electromagnetic lock judges induced current test point of the signal on transformer high-voltage cable connector pedestal,
With the characteristic being connected directly with buried change, easy access personnel make visualization to electrification situation and judge；
The invention has the advantages that can intuitively and effectively ensure the same of personnel's electric shock-prevention safety using electromagnetic lock
When, the surfacing of melt pit upper sealing plate is ensured using the double-deck manhole cover structure and avoids electromagnetic lock fail in compression.
Description of the drawings
Fig. 1 is the structure chart of the double-deck manhole cover for buried change melt pit entrance security protection of the present invention；
Fig. 2 is the usage state diagram (front view) of the double-deck manhole cover of the present invention；
Fig. 3 is the usage state diagram (vertical view) of the double-deck manhole cover of the present invention.
Specific implementation mode
It is right below in conjunction with the accompanying drawings in order to make those skilled in the art be better understood when technical scheme of the present invention
Its specific implementation mode is described in detail：
It please refers to Fig.1, Fig. 2 and Fig. 3, highly preferred embodiment of the present invention, one kind are protected for buried change melt pit entrance security
The double-deck manhole cover, include the electromagnetic lock 4 of upper layer lid 31, lower layer's lid 32 and integrated electrification display.Buried change includes position
Babinet 1 more than ground and the pedestal 2 to locate below ground level,.
Upper layer lid 31 and lower layer's lid 32 are arranged one on the other in the buried top for becoming melt pit entrance；Electromagnetic lock 4 is pacified
On lower layer's lid 32, by manhole cover forced blocking；The electrification of electromagnetic lock 4 judges transformer high-voltage of the signal quoted from buried change
Induction coil on cable connector pedestal, convenient for personal observations judge electrification situation, electromagnetic lock 4 by buried change transformer low voltage
Side provides working power.
Referring to Fig. 3, the double-deck manhole cover for buried change melt pit entrance security protection of the present invention, is located at transformer room
Internal clearance larger part is cheated in high-pressure side, is passed in and out convenient for personnel.Using electromagnetic lock 4 forced blocking function and manual unlocking function over the ground
It cheats entrance and carries out security protection.Manhole cover is double-layer structure, and lower layer's lid 32 is mounted with the electromagnetic lock of integrated electrification display, on
Layer lid 31 ensures that melt pit upper sealing plate appearance is smooth, and avoids electromagnetic lock fail in compression.
In conclusion the double-deck manhole cover for buried change melt pit entrance security protection of the present invention, can utilize electromagnetism
While lock intuitively and effectively ensures personnel's electric shock-prevention safety, ensure that melt pit upper sealing plate surface is flat using the double-deck manhole cover structure
It is whole and avoid electromagnetic lock fail in compression.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
