Abstract
The utility model relates to an electrified display, and in particular discloses an embedded type high-voltage electrified display device. The embedded type high-voltage electrified display device comprises an insulator, and is characterized in that an induction electrode is directly poured into the insulator; and an electrode lead of the induction electrode is exposed from the insulator and is connected with the high-voltage electrified display directly. The embedded type high-voltage electrified display device is simple in structure, attractive in appearance, low in cost, safe and reliable, the conventional complex structure of opening on a shell, supporting for fixing and gas sealing is changed, and damage of insulation breakdown, local discharge and the like is avoided.
Description
(1) technical field
The utility model relates to a kind of electrification display, particularly a kind of flush type high voltage display device.
(2) background technology
Present stage, 110KV and above SF
6The structure of the charged display device of Cubicle Gas-Insulated Switchgear is; Increase by a joint bus bar canister; On bus bar canister, open three holes (three-phase combined type structure) or a hole (single busbar structure); Then induction electrode is deep into bus bar canister inside through bracing frame, makes every phase induction electrode, and isolate induced signal with induction electrode through insulation and cause outside and be connected with electrification display apart from this phase conductor certain distance; Its complex structure, manufacturing cost is high, is prone to puncture, and is prone to gas leakage, and office's value of putting increases poor reliability.
(3) summary of the invention
The utility model is in order to remedy the deficiency of prior art, and a kind of flush type high voltage display device of simple in structure, stable performance is provided.
The utility model is realized through following technical scheme:
A kind of flush type high voltage display device comprises insulator, it is characterized in that: said insulator inside directly is cast with induction electrode, and the contact conductor of induction electrode exposes exterior insulator and directly is connected with high-voltage charge display device.
The utility model casts directly over insulator inside with induction electrode and contact conductor; Contact conductor exposes exterior insulator and directly is connected with display, and during electrification in high voltage, induction electrode induces voltage signal; Whether charged through electronics enlarged and displayed high-pressure conductor, and can realize electrical interlocks.
The more excellent scheme of the utility model is:
Said induction electrode is a copper mesh; The three-phase induction electrode is cast near the three-phase conductor respectively, and keeps certain insulation distance, during electrification in high voltage 5 ~ 20mV voltage signal can be provided; The voltage signal that induces through induction electrode shows whether high pressure is charged, and has the output of electric shock and other functions chain.
The utility model is simple in structure, good looking appearance, and cost is low, and is safe and reliable, and the labyrinth of perforate on housing before having changed, support fixation, air seal has avoided insulation breakdown, office to put harm such as increase.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Among the figure, 1 insulator, 2 induction electrodes, 3 high-voltage charge display devices.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises insulator 1, and said insulator 1 inside directly is cast with induction electrode 2, and the contact conductor of induction electrode 2 exposes insulator 1 outside and directly is connected with high-voltage charge display device 3; Said induction electrode 2 is a copper mesh, and three-phase induction electrode 2 is cast near the three-phase conductor respectively.
Netted induction electrode 2 is cast directly over insulator 1 inside; Contact conductor exposes insulator 1 outside and directly is connected with high-voltage charge display device 3, and during electrification in high voltage, induction electrode 2 induces 5 ~ 20mV voltage signal; Whether charged through electronics enlarged and displayed high-pressure conductor, and can realize electrical interlocks.
This design is mainly used in the SF of 110KV and above electric pressure
6Cubicle Gas-Insulated Switchgear.
