Abstract
The utility model discloses an outdoor vacuum circuit breaker. A technical scheme is characterized in that the circuit breaker comprises a box body, a circuit breaker body arranged on the box body and an operating mechanism; the circuit breaker body comprises an insulation sleeve, an upper wire outlet terminal and a lower wire outlet terminal; a current transformer is arranged between the lower wire outlet terminal and the circuit breaker body; the circuit breaker body is electrically connected with a lead which is electrically connected with the current transformer; increase climbing groups are arranged on one side of the current transformer corresponding to the lower wire outlet terminal and one side of the current transformer corresponding to the circuit breaker body; the increase climbing groups are made of silicon rubber. A composite external insulation structure is formed. Excellent hydrophobicity and hydrophobic migration of the silicon rubber are used so that stable and safe operation of the current transformer is ensured and usage safety can be guaranteed strongly.
Description
Technical field
The utility model relates to a kind of circuit breaker, and more particularly, it relates to a kind of outdoor vacuum circuit breaker.
Background technology
Vacuum circuit-breaker refers to the circuit breaker of contact in the bubble of high vacuum deciliter, because the dielectric in contact gap after its arc-extinguishing medium and arc extinguishing is all that high vacuum is gained the name.
Vacuum circuit-breaker mainly is comprised of support, insulated part, operating mechanism, running part, vacuum interrupter, current-carrying part.Support is the support body that each functional unit is installed; Insulated part gets up to satisfy the insulating requirements of circuit breaker with each functional frame; Operating mechanism is the Power Drive Unit that circuit breaker closes, divides; Running part is delivered to arc control device to the motion of actuating part, realizes the closing of arc control device, sub-switching operation; Vacuum interrupter is to realize that the Guan Heyu of circuit cut-offs the breath arc element of function; The moved end of current-carrying part and arc control device and quiet end connect and compose current channel.
At present, the outdoor vacuum circuit breaker on market is provided with current transformer between lower wire end and breaker body, and breaker body is electrically connected with the wire that is electrically connected to current transformer.Set up current transformer on vacuum circuit-breaker, electric current or short-circuit protection to vacuum circuit-breaker can be provided, the current acquisition signal can also be provided for the intelligent controller in vacuum circuit-breaker.But because current transformer is just realized simple the connection between the two with lower wire end, electrical circuit breakers body simply, current transformer itself can not get effective protection, thereby makes vacuum circuit-breaker use safety to can not get powerful assurance.
The utility model content
Deficiency for the prior art existence, the purpose of this utility model is to provide a kind of outdoor vacuum circuit breaker, this circuit breaker utilizes hydrophobicity and the migration of hydrophobicity of silicon rubber excellence, guarantee that current transformer is stable, operation safely, thereby the safety of using can access powerful assurance.
for achieving the above object, the utility model provides following technical scheme: a kind of outdoor vacuum circuit breaker, comprise casing, be placed in breaker body and operating mechanism on casing, described breaker body comprises insulating sleeve, upper outlet terminal and lower wire end, be provided with current transformer between described lower wire end and breaker body, described breaker body is electrically connected with the wire that is electrically connected to current transformer, corresponding lower wire end of described current transformer one side, corresponding breaker body one side of current transformer is equipped with to increase climbs the group, described increase climb group made by silicon rubber.
By adopting technique scheme, consisted of the combined type external insulation structure, utilize hydrophobicity and the migration of hydrophobicity of silicon rubber excellence, guarantee that current transformer is stable, operation safely, thereby the safety of using can access powerful assurance.
The utility model further is set to: described breaker body comprises full skirt shape insulation crust, and described full skirt shape insulation crust comprises along large full skirt and the little full skirt of the interval setting of same central axis.
By adopting technique scheme, be in due to little full skirt under the protection of large full skirt, vulnerable to pollution, be not difficult for forming the curtain of rain, improves insulating properties, hydrophobicity, self-cleaning.
The utility model further is set to: described insulating sleeve is made of methyl vinyl silicone rubber.
By adopting technique scheme, the silicon rubber main chain is Si-O key, and bond energy is up to 445kJ/mol, far above solar ultraviolet heat input (398kJ/moI), therefore, when lightning arrester uses for a long time in the open air, ultraviolet ray can not disconnect Si-O key, and silicon rubber cracking, " efflorescence " phenomenon do not occur.
Description of drawings
Fig. 1 is the structural representation one of the utility model outdoor vacuum circuit breaker embodiment;
Fig. 2 is the structural representation two of the utility model outdoor vacuum circuit breaker embodiment.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model outdoor vacuum circuit breaker embodiment is described further.
A kind of outdoor vacuum circuit breaker, comprise casing 1, be placed in breaker body 2 and operating mechanism on casing 1, described breaker body 2 comprises between insulating sleeve 21, upper outlet terminal 22, lower wire end 23, described lower wire end 23 and breaker body 2 and is provided with current transformer 3, described breaker body 2 is electrically connected with the wire 5 that is electrically connected to current transformer 3, the corresponding lower wire end of described current transformer 3 23 1 sides, corresponding breaker body 2 one sides of current transformer 3 are equipped with to increase climbs group 4, and described increasing climbs group 4 and made by silicon rubber.
By adopting technique scheme, consisted of the combined type external insulation structure, utilize hydrophobicity and the migration of hydrophobicity of silicon rubber excellence, guarantee that current transformer 3 is stable, operation safely, thereby the safety of using can access powerful assurance.
Described breaker body 2 comprises full skirt shape insulation crust 24, and described full skirt shape insulation crust 24 comprises along large full skirt 241 and the umbellule skirt 242 of the interval setting of same central axis.
By adopting technique scheme, be in due to umbellule skirt 242 under the protection of large full skirt 241, vulnerable to pollution, be not difficult for forming the curtain of rain, improves insulating properties, hydrophobicity, self-cleaning.
Described insulating sleeve 21 is made of methyl vinyl silicone rubber.By adopting technique scheme, the silicon rubber main chain is Si-O key, and bond energy is up to 445kJ/mol, far above solar ultraviolet heat input (398kJ/moI), therefore, when lightning arrester uses for a long time in the open air, ultraviolet ray can not disconnect Si-O key, and silicon rubber cracking, " efflorescence " phenomenon do not occur.
