Abstract
The utility model discloses a distribution insulation protecting structure of a distribution cabinet. The distribution insulation protecting structure comprises a drawer unit chamber, wherein the drawer unit chamber is internally provided with a drawer unit, a terminal chamber, a rear cable chamber, a primary coil out cover, a small row support and front and rear chamber partition plates; the key point is that the drawer unit is provided with a primary moving plug-in unit, a position of the rear cable chamber, which is corresponding to the position of the primary moving plug-in unit, is provided with a primary coil in cover, a vertical bus is arranged above the primary coil in cover, and the periphery of the vertical bus is also provided with a vertical bus cover; and rectangular holes are formed in the primary coil in cover and are matched with a contact of the primary moving plug-in unit, and the primary moving plug-in unit is convenient to contact with the vertical bus arranged above the primary coil in cover through the rectangular holes. The distribution insulation protecting structure provided by the utility model has the advantages that the structure is simple, and the traditional valve structure of the distribution cabinet is replaced with a primary moving plug-in unit structure, so that the distribution insulation security is high, and the distribution insulation protecting structure is not easy to damage and is reliable and durable.
Description
Technical field
The utility model relates to a kind of distribution isolating and protecting device of controller switching equipment.
Background technology
What the moving dongle configuration of the drawer of existing power distribution cabinet adopted usually is valve mechanism, realizes the distribution insulation blocking with this.The moving plug-in unit of drawer is opened valve and enter by the flange on drawer before entering the service position; When drawer withdraws from, chamber isolation before and after valve is closed and made.This valve mechanism is in assembling and use procedure, and valve structure spare often is damaged when the drawer promotion position because of factors such as quality of materials.In case after damaging, be difficult to repair, the user directly splits out valve structure spare usually, will make like this isolating and protecting afunction of its power distribution cabinet, thereby potential safety hazard occur.
The utility model content
The purpose of this utility model is to provide a kind of distribution insulation blocking structure of reliability and durability power distribution cabinet.
To achieve these goals, by the following technical solutions, a kind of distribution insulation blocking structure of power distribution cabinet; comprise the drawer unit chamber, drawer unit is indoor a drawer unit, the terminal chamber; rear cable vault; an outlet hood, float holder, chamber, front and back dividing plate; it is characterized in that: have once moving plug-in unit on described drawer unit; rear cable vault is arranging the inlet wire cover one time with moving card address corresponding position once, and this inlet wire cover top has vertical bus, and the periphery of vertical bus also is provided with the vertical bus cover.
Have rectangular opening on a described inlet wire cover, this rectangular opening adapts with the contact of moving plug-in unit once, and the contact of being convenient to once to move plug-in unit contacts with vertical bus above it by described rectangular opening.
The utility model is simple in structure, and the valve structure that power distribution cabinet is traditional replaces with once moving dongle configuration, makes the fail safe of distribution isolation higher, and not fragile, more reliability and durability.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figures 1 to 4; a kind of distribution insulation blocking structure of power distribution cabinet; comprise the drawer unit chamber 5 that is positioned at the power distribution cabinet front end; drawer unit 1 is arranged in drawer unit chamber 5; terminal chamber 10 is positioned at the rear cable vault 3 of power distribution cabinet rear end in addition, outlet hood 11 once in rear cable vault 3; float holder 8, chamber dividing plate 4 before and after having between the front and back end.
Have once moving plug-in unit 2 on described drawer unit 1, rear cable vault 3 is arranging inlet wire cover 7 one time with moving plug-in unit 2 corresponding positions, position once, and the top of this inlet wire cover 7 has vertical bus 9, and the outside of vertical bus 9 also is provided with vertical bus cover 6.Have rectangular opening 7-1 on a described inlet wire cover 7, this rectangular opening 7-1 and the contact 2-1 of moving plug-in unit 2 once adapt, and the contact 2-1 of being convenient to once to move plug-in unit contacts with vertical bus 9 above it by described rectangular opening 7-1.
In use, drawer unit is inserted drawer unit indoor, promote drawer unit, make the once moving plug-in unit at rear travel forward, until its contact arrives the position of an inlet wire cover, owing to being provided with rectangular opening on an inlet wire cover, making vertical bus can see through rectangular opening and contact with the contact that once moves plug-in unit, thereby enter operating state.Owing to being provided with the vertical bus cover in the vertical bus periphery, therefore, once the contact of moving plug-in unit in the cable vault except with vertical bus contacts, can not contact with other unit and structural member, thereby realized the isolation between each unit, guarantee each unit safe operation, discrete component breaks down can not cause impact on other elements yet.
When needs, drawer unit is safeguarded or when overhauling, directly drawer unit is pulled out, at this moment, once the contact of moving plug-in unit separates with vertical bus, makes the drawer unit chamber of rear cable vault and front end thoroughly separate, and the rectangular opening that adds on last inlet wire cover is very little, therefore, the electric component of cable vault after the operating personnel of cup can not touch is realized the safeguard function of cup operation has been avoided the appearance of potential safety hazard.
The utility model is simple in structure, and the valve structure that power distribution cabinet is traditional replaces with once moving dongle configuration, makes the fail safe of distribution isolation higher, and not fragile, more reliability and durability.
