Description
Technical field
This utility model relates to electric switch equipment technical field, particularly relates to a kind of switchgear arc-chutes.
Background technology
Switchgear be electrically in most important equipment, be power system to control and the key equipment of protection circuit.Switchgear is when Guan Bi or open-circuit line, the strongest high-temperature electric arc can be produced between point contact closing, the electric arc especially produced when high-tension circuit disjunction, involutory point of contact has the biggest destruction, and how effectively to extinguish electric arc is the key technology in switchgear.At present in alternating-current switch field, low voltage switch equipment mainly uses air dielectric to carry out normality or air pressing type blow-out；High-tension switch gear mainly takes the methods such as insulating oil, air air pressing type, sulfur hexafluoride gas or vacuum magnetic field rotation arc to carry out blow-out.In dc switch basin, owing to unidirectional current does not has zero crossing, so at low-voltage direct electrical domain, mainly under air dielectric state, using the methods such as many grids, superposition alternating current circuit or magnetic field rotation arc to carry out blow-out；High pressure and extra-high voltage field use semiconductor direct current valve to carry out circuit conjunction point.In sum, prior art mainly uses gaseous medium, liquid medium, vacuum magnetic field rotation arc to carry out blow-out without the such three kinds of states of medium, does not carry out the technology of arc extinguishing with solid state medium.
Utility model content
The purpose of this utility model is to provide a kind of Novel arc extinguishing room, utilizes nanometer insulation meterial as arc-extinguishing medium, has the advantage that arc extinguishing ability is strong.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of Novel arc extinguishing room, the moving contact including housing and being arranged on housing two ends and static contact, static contact is connected by the first end seal lid and housing seal are fixing, moving contact is flexibly connected with housing seal by the second end seal lid, being filled with insulant in described housing, described insulant uses nanometer insulation meterial.
Described nanometer insulation meterial uses the nanometer insulation meterial that size is 20 microns to 30 microns through spheroidising.
The height of the nanometer insulation meterial filled in described housing at least can cover the position that moving contact contacts with static contact.
Described nanometer insulation meterial uses nano ceramic material, nano-macromolecule material or aeroge.
Described nano ceramic material uses the nano ceramic material being mainly composed of silicon dioxide or aluminium oxide.
It is provided with fairlead between described moving contact and the second end seal lid, fairlead is set on moving contact, fairlead is connected by corrugated tube and bellow seal cover are fixing, and described corrugated tube and bellow seal cover are all set on moving contact, and bellow seal cover is fixed with moving contact and is connected.
Described moving contact and static contact use plug in construction, cut-in type structure or plane contact type structure.
When described moving contact and static contact use plug in construction, the end face that moving contact and static contact contact all scribbles ceramic coating.
This utility model simple in construction, will do application of vacuum and encapsulates the nanometer insulation meterial of spheroidising, utilize insulating properties, heat conductivility, high fluidity energy and resistance to elevated temperatures that nanometer insulation meterial is good, reach the purpose of arc extinguishing inside arc-chutes.Nanometer insulation meterial becomes spherical particle after spheroidising, when contact disjunction campaign, spherical particle flows with contact, thus arc physics is blocked, spherical particle elongating arc between two contacts length in the electric field, conduct heat to rapidly peripheral granule with the spherical particle of arc contacts, make arc temperature reduce, be achieved in physical property blow-out；Meanwhile, adsorbing the metal ion in arc light with the spherical particle of arc contacts, there is local sintering or gasification in spherical particle under arc light high temperature action, so that arc temperature reduces, reaches blow-out purpose；The end that moving contact contacts with static contact all scribbles ceramic coating, ceramic coating can elongating arc, accelerate electric arc cooling.

Detailed description of the invention
nullAs shown in Figure 1 to Figure 3，This utility model includes housing 3，It is vacuum in housing 3，In the present embodiment，Housing 3 uses porcelain shell，And housing 3 is cylindrical，Housing 3 be respectively arranged at two ends with moving contact 6 and static contact 1，Static contact 1 is sealedly and fixedly connected with housing 3 by the first end seal lid 10，Moving contact 6 is connected with housing 3 air-tight movable by the second end seal lid 8，First end seal lid 10 and the second end seal lid 8 use stainless steel material，It is provided with fairlead 7 between moving contact 6 and the second end seal lid 8，Fairlead 7 is set on moving contact 6，Fairlead 7 seals，Fairlead 7 is connected by corrugated tube 5 is fixing with bellow seal cover 9，Corrugated tube 5 and bellow seal cover 9 are all set on moving contact，And bellow seal cover 9 and moving contact are fixing is connected，Bellow seal cover 9 and corrugated tube 5 are existing apparatus，Repeat no more.During moving contact 6 moves up and down, bellow seal cover 9 moves up and down with moving contact 6, and corrugated tube about 5 stretches, and does not affect the vacuum state in arc-chutes.
Vacuum position in cylindrical housings 3 is filled with insulant 2, insulant 2 uses the nanometer insulation meterial that size is 20 microns to 30 microns through spheroidising, in the present embodiment, nanometer insulation meterial uses nano-macromolecule material, aeroge or is mainly composed of the nano ceramic material of silicon dioxide or aluminium oxide, when moving contact 6 and static contact 1 close, the height of nanometer insulation meterial at least should can cover the position that moving contact 6 contacts with static contact 1.When contact disjunction campaign, nanometer insulation meterial flows with contact, thus arc physics is blocked, spherical particle between two contacts can elongating arc length in the electric field, peripheral granule is conducted heat to rapidly with the spherical particle of arc contacts, make arc temperature reduce, be achieved in physical property blow-out；Meanwhile, can adsorb the metal ion in arc light with the spherical particle of arc contacts, there is local sintering or gasification in spherical particle under arc light high temperature action, so that arc temperature reduces, reaches blow-out purpose.
Moving contact 6 and static contact 1 use plug in construction, during combined floodgate, moving contact 6 inserts static contact 1, ceramic coating 4 is all scribbled on the end face that moving contact 6 contacts with static contact 1, ceramic material can elongating arc, accelerating the cooling of electric arc, the plug in construction of moving contact 6 and static contact 1 is existing structure, repeats no more.Additionally, moving contact 6 and static contact 1 also can use cut-in type structure or plane contact type structure, cut-in type structure and plane contact type structure to be existing structure, repeat no more.
Operationally, when keeping at a certain distance away between moving contact 6 and static contact 1, arc-chutes are in disjunction state to this utility model, and galvanic circle is cut off；When moving contact 6 contacts with static contact 1, arc-chutes are in the state of closing, and galvanic circle is connected.Separating and in closing course with static contact 1 at moving contact 6, nanometer insulation meterial can suppress generation and the expansion of electric arc effectively, it is ensured that switchs folding effectively.
