In receiving and with electric energy, and control protection, monitoring and measuring are carried out power circuit.Intermediate switchgear cabinet is mainly used in generating electricity
Factory, the power transmission of medium and small generator, power system secondary substation by electricity, power transmission, the distribution of industrial and mineral enterprises and institutions, and
Starting of Large-scale High-Pressure motor etc..Its cabinet body structure is generally divided into 4 cells, is respectively：Control room, bus-bar room, breaker
Room and cable vault.Because its structure has the anti-interlock of good five and preferable electric property, so in current distribution products
In occupy an leading position.
In middle-placed switch cabinet structure, the spatial design of breaker chamber is extremely compact, and the contact box ABC three-phases of high current are almost
Installed in the state of adjacent, contact box is typically the insulating part that vacuum is poured, although from design standard it has been specified that
The electric clearance and the minimum definite value of creep age distance of each voltage class, but after the operation regular hour, due to insulation
Material receives damage or environmental variance is changed, such as filth, when the humidity of breaker chamber is larger and during relatively low temperature, Jiu Huifang
When raw condensation, particularly breaker are in operating position, after circuit breaker contact arm is powered, form stronger on contact arm periphery
Electric field, electric discharge phenomena are ironed so as to promote to free sudden strain of a muscle along side in contact box insulating part, with partial discharge continue and discharge capacity increase,
Ultimately result in breaker chamber and arc discharge short circuit accident occur.So it is breakneck that sudden strain of a muscle, which occurs, for breaker chamber to iron electric discharge, dodge
Iron be also controller switching equipment safe operation main harm.Then the breaker chamber in middle-placed switch cabinet and cable vault, are usually provided with adding
Hot damp-eliminating apparatus, to ensure that breaker and contact box produce partial discharge because being influenceed by moisture at work, but installs heating additional
Device goes the scheme of moisture not can effectively solve the problem that the phenomenon of contact box condensation, is less avoided that the office caused by contact box condensation
Put phenomenon.The use of another heater can cause the insulating device nearer apart from heater to be heated accelerated ageing, cause other failures.
In this case, in the market exigence one kind can breaker prevent circuit breaker contact arm and contact box from discharging
Device, to tackle the defect of the above, and ensure the safe operation of equipment.
Utility model content
The purpose of this utility model be to overcome in place of the deficiencies in the prior art there is provided one kind be used for fixed sealing type breaker with
The anti-partial discharge sealing sheath of contact box.
The utility model solves its technical problem and takes following technical scheme to realize：
It is a kind of to be used for the anti-partial discharge sealing sheath of fixed sealing type breaker and contact box, installed in for the disconnected of detection contact box
On the device of road, breaker includes the contact arm of upper and lower two cantilever structures, and the cantilever end of contact arm is coaxially fixed with a plum blossom and touched
The outer coaxial sleeve of head, the Mume flower contact and contact arm is equipped with a contact arm set, it is characterised in that：In contact arm sleeve pipe and breaker body
Contact position periphery is set with a sealing sheath, and the sealing sheath includes circuit breaker contact arm sheath, sheath telescopic joint and guiding
Correct boss, circuit breaker contact arm sheath, sheath telescopic joint and be oriented to correction boss sequentially coaxially order set and integrally into
Type is made.
Moreover, the circuit breaker contact arm sheath and guiding correction boss are cylinder barrel shaped structure.
Moreover, the sheath telescopic joint is two outer bulge loops being coaxially linked in sequence.
Moreover, the sealing sheath is entirety is molded sulfidization molding using silicon rubber material grinding tool.
Advantage of the present utility model and good effect are：
1st, this sealing sheath can preferably seal the space between breaker and contact box, it is to avoid humid air, corruption
Corrosion gas and filthy particle enter the possibility of contact box
2nd, breaker chamber can cancel the design of heater, save material cost, and equipment cost is relatively low, it is adaptable to
Large-scale production
3rd, double telescopic joint compressions can preferably ensure the sealing property of sealing sheath and contact box contact
4th, the utility model preferably resolves contact box partial discharge phenomenon caused by moisture and filth, it is to avoid electric discharge thing
Therefore generation, extend the service life of controller switching equipment, ensured the safe operation of equipment.

Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, following examples are to retouch
The property stated, be not limited, it is impossible to limit protection domain of the present utility model with this.
It is a kind of to be used for the anti-partial discharge sealing sheath of fixed sealing type breaker and contact box, installed in for the disconnected of detection contact box
On the device of road, breaker includes the contact arm 3 of upper and lower two cantilever structures, and the cantilever end of contact arm is coaxially fixed with a plum blossom and touched
First 4, the Mume flower contact and the outer coaxial sleeve of contact arm are equipped with a contact arm sleeve pipe 2；
Innovative point of the present utility model is：
