Description
The utility model relates to the install bin of a kind of improved electrical instrumentation or control panel, belongs to the distribution board technical field.
At present, make at finish coatings after most electrical instrumentation control cabinets all adopt the sheet metal punch forming again, because of the metal material easy-to-rust, make control cabinet shortening service life, this shortcoming at damp-heat area more so; And the metal control cabinet is on-insulated, also has problems aspect fail safe, so must install earth connection additional.
In addition, many electrical instrumentation control cabinets all wish to have anti-operation against rules the against regulations or anti-electricity-theft device, to guarantee safety utilization of electric power or to stop non-part of the unprincipled fellow think, yet, also since in the past most electrical instrumentation control cabinets all adopt metal material to make, therefore the bad solution of its electromagnetic induction problems should not install the anti-violating the regulations or anti-electricity-theft device of doing triggering source (such as tongue tube and so on) with electromagnetic induction.
The purpose of this utility model is to propose a kind of long electrical instrumentation control cabinet of stronger antirust function, useful life that has.
The purpose of this utility model is to realize like this;
A kind of electrical instrumentation control cabinet, it comprises casing 1, mounting panel 2, chamber door 3, input terminal 11, lead-out terminal 21, its basic improvements are: casing 1, mounting panel 2, chamber door 3 is a nonmetal plate, mounting panel 2 is fixed on the self expansion slide plate 5, in each dovetail groove 4 one or more slide plates 5 that opening 20 is arranged can be housed, four jiaos of casing respectively have a dovetail groove 4, tensioner screw 6 is arranged on the slide plate 5, can layering be installed by jamproof barricade, heating panel and other functional device plates also are equipped with ground connection busbar 9 on mounting panel 2, input terminal 11, lead-out terminal 21, chamber door 3 is provided with observation window 12.
Above-mentioned electrical instrumentation control cabinet, described mounting panel 2 is divided into gauge field and control assembly district, is provided with dividing plate 10 between the district, be divided into two-chamber or multi-cavity, described dividing plate dual-side inserts respectively in two slot 16s of box inside wall, and its inner side edge is near mounting panel 2, and outer side edges is near the inboard of chamber door 3.
Above-mentioned electrical instrumentation control cabinet, described mounting panel 2 also can be installed on the triangle fixed head 18 that is welded in 1 four jiaos of casings;
Above-mentioned electrical instrumentation control cabinet, tongue tube 7 is inlayed in the inside edge of described dividing plate 10, with the mounting panel 2 of tongue tube 7 opposite positions on permanent magnet 8 is housed.
Above-mentioned electrical instrumentation control cabinet, the number of described tongue tube 7 and permanent magnet 8 is corresponding with the control number of phases, and tongue tube 7 is serially connected in the live wire circuit, and its operating current is 1.25 times of circuit rated current.
Above-mentioned electrical instrumentation control cabinet, described anti-electricity-theft device are that the mounting distance between tongue tube 7 and the permanent magnet 8 is the 1.5-3 millimeter.
The utility model is owing to adopt nonmetallic materials such as polyvinyl chloride adds glass fibre etc. and makes casing, mounting panel, chamber door etc., so acid and alkali resistance, salt corrosion, antiultraviolet insulate, fire-retardant, resistance to compression, antivibration, shock resistance, can reach 30-50 its useful life; Anti-operate against regulations and anti-electricity-theft device can make operating personnel operate easily and can't relocate without authorization, in case violating the regulations relocating, then must moveable partition board or face shield and cause electric power disconnection, make the management of power use safer.
The utility model also is easy to adopt modular organization design and instrument control mounting panel position adjustable, therefore can with the meter of any specifications and models can instrument, supporting uses such as automatic air-break switch, earth leakage protective device; Can guarantee that the meter energy instrument that need observe is in the best transparent effect position of observation window, is convenient to read with observing apparatus dynamic.The utility model box sealing is better, can avoid the influence of sand and dust, etchant gas and vibration.
