Technical field:
The present invention relates to a kind of fully-insulated waterproof switch cabinet
Background technology:
The patent No. is the sulfur hexafluoride gas-insulating metal enclosed switchgear of [02257628.2] disclosed a kind of utility model, its structure is that the circuit breaker that has three-station is installed in the inflation casing that is filled with sulfur hexafluoride gas, connect by having the outer conehead of bubble-tight cable, bus tie and loop, the inflation casing is installed on the base of cabinet, and the mechanism of cabinet and control room are installed on the inflation casing.Though this invention volume only is 60% of an air insulation switchgear, reduced installing space, one time the major loop live part is not affected by the external environment, but the operating mechanism of switch and secondary control protection system (the digital control and protective device of integrated form) place atmosphere, easily affected by environment, in case can not continuous service by water logging; Sulphur hexafluoride produces multiple poisonous, corrosive gas under corona, spark and arc discharge effect simultaneously, can cause certain pollution to environment, and is not easy to overhaul after the components and parts fixed installation.
Summary of the invention:
The purpose of this invention is to provide a kind of fully-insulated waterproof switch cabinet, the not only safe and reliable environmental protection of this fully-insulated waterproof switch cabinet, and also simple and compact for structure, volume is little, is easy to maintenance, and water logging does not in a short time have sustainable operation.
Fully-insulated waterproof switch cabinet of the present invention, comprise cabinet, be provided with bus-bar room in the cabinet, breaker chamber and cable vault, it is characterized in that: be provided with the portable circuit breaker of isolating moving contact that has that is positioned on the guide rail in the described breaker chamber, also be provided with the isolation fixed contact in the described breaker chamber, described isolation fixed contact comprises that the bus end is isolated fixed contact and cut cable is isolated fixed contact, described bus end is isolated fixed contact and is connected with the branch bar nipple that gos deep into breaker chamber, described cut cable is isolated fixed contact and is connected with the cable nipple that gos deep into breaker chamber, described breaker chamber is airtight fully, and is provided with openable air-tightness shrouding.
Distinguishing feature of the present invention: kept air-insulated intermediate switchgear cabinet on the one hand, assembled the circuit breaker that to remove, realized that circuit breaker exchanges, with maintenance, the replacing of other components and parts in the cabinet; Overcome the shortcoming that mid-cabinet is subject to harm such as condensation, filth in the environment again.
On the other hand, not only kept major loop components and parts advantage not affected by environment in the inflation cabinet, and digital control and protective device places in the sealed air chamber with the operating mechanism of circuit breaker and integrated form, has realized the protection to them; Overcome the shortcoming that components and parts can not keep in repair, change and need fill the sulphur hexafluoride pressed gas in the sealed air chamber of welding again, filled common gases in the atmospheric pressure lower seal air chamber and can realize miniaturization.
