Abstract
The utility model discloses a kind of 10kV semi-insulating ring main unit earthing switching signal device, it is characterized in that: on earthing, install auxiliary contact, auxiliary contact are contacted by electric loop and an indicator light.Device can ensure that semi-insulating ring main unit body dimension is less.Device solves in prior art can only observe the position of the switch and opening and closing state by the state position observation window being arranged at gas tank front end, cause easily occurring erroneous judgement, the personal safety of difficult judgment and Operation and Maintenance personnel cannot obtain Reliable guarantee, also cannot ensure the problems such as the operational reliability of equipment simultaneously.And device is safeguarded simple, life cycle is long.
Description
Technical field
The utility model belongs to controller switching equipment, particularly relates to a kind of 10kV semi-insulating ring main unit earthing switching signal device.
Background technology
In upgrading urban and rural power grids with in building, carry out ring network power supply, even if with cable, by cable arrangements in underground, and connect into looped network loop.The interruption of power supply can be reduced like this, greatly reduce provisional fault simultaneously.
Ring main unit load switch must confirm cabinet door before combined floodgate power transmission, and locking is firm; Grounding switch indeed pulls open; Switch is really at run location.Car switch must confirm that before being operated to closing position by open position earthed switch is at open position, forbids road with ground to close a floodgate.
Current ring main unit only observes the position of the switch and opening and closing state by the state position observation window being arranged at gas tank front end, ring main unit (electronic) scheme is that on-load switch opening and closing state has signal lamp to feed back, and earthed switch does not but have, can only observe by position observation window, this present situation can cause the personal safety of Operation and Maintenance personnel to obtain Reliable guarantee, also cannot ensure the operational reliability of equipment simultaneously.
Summary of the invention
For prior art Problems existing, the utility model proposes a kind of earthing switching signal device and can make up this technical disadvantages, can the effective guarantee person and device security.
Because semi-insulating ring main unit body dimension is less, and earthing is in cable vault, space is more nervous, and the ground cutter position detection that achieves a butt joint can only install sensitive switch additional on former earthing moving component, by changing semi-insulating ground cutter blade and connecting rod layout, redesign ground swivel axle, for apparatus for auxiliary contact designs reserved installation site, need to ensure that the safe distance of contact and high-pressure section divides whole shaft simultaneously and carry out vulcanizing treatment, prevent interference, thus realize the reliable Detection of position.
The advantage that the utility model compared with prior art has is: ensure that semi-insulating ring main unit body dimension is less, solve in prior art and can only observe the position of the switch and opening and closing state by the state position observation window being arranged at gas tank front end, cause easily occurring erroneous judgement, the personal safety of difficult judgment and Operation and Maintenance personnel cannot obtain Reliable guarantee, also cannot ensure the problems such as the operational reliability of equipment simultaneously.And device is safeguarded simple, life cycle is long.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Former ring main unit only observes the position of the switch and opening and closing state by the state position observation window being arranged at gas tank front end, ring main unit (electronic) scheme is that on-load switch opening and closing state has signal lamp to feed back, and earthed switch does not but have, can only observe by position observation window.This device solved by design ring main unit earthing switching signal device easily there is erroneous judgement, the personal safety of difficult judgment and Operation and Maintenance personnel cannot obtain Reliable guarantee, also cannot ensure the problems such as the operational reliability of equipment simultaneously.
Fig. 1 is the principle schematic of earthing switching signal device of the present utility model, that specify the theory structure of the utility model earthing switching signal device, and Fig. 2 is the earthing-fuse base structural representation of ring main unit, and Fig. 3 is the structure chart of ring main unit.This device is arranged on fuse installing rack 6, by installing sensitive switch additional in former earthing moving component earthing blade 1 grade, also be auxiliary contact 3, by adjustment earthing blade and connecting rod 7 layout, redesign ground swivel axle 2, and auxiliary contact 3 and indicator light 4 are connected in live locking loop, locked loop input operation voltage 5, reaches monitoring earthing and opens a sluice gate and combined floodgate.Ensure the safe distance of contact and high-pressure section in an installation, vulcanizing treatment is carried out to whole rotating shaft 8 simultaneously, prevent interference, thus realize the reliable Detection of position.
The technical indicator of device is: device external agency bending strength is more than or equal to 270MPa, and device appliance life (electrical equipment is without maintenance) is greater than 6000 times, and device for mechanical stability is greater than 5000, given signal of telecommunication action rate 100%.Device specified power frequency 1min withstand voltage (alternate and to mutually ground) is more than or equal to 65kV; Device rated lightning impulse withstand voltage peak value (1.2/50 μ s) (alternate and to mutually ground) is more than or equal to 125kV; Rated lightning impulse withstand voltage peak value (1.2/50 μ s) (isolation fracture) is more than or equal to 145kV.Compound inslation material thickness is more than or equal to 6mm, proportion: 11KG/m2; Device retting-flax wastewater is more than or equal to 3.1cm/kV.
The foregoing is only the preferred embodiment of the present invention; not limit practical range of the present invention with this, all persons that is familiar with technique, use principle of the present invention and technical characteristic; the various change done and decoration, all should be covered by within protection category that these claims define.
