Abstract
The invention discloses a 35kV movable-type switch cabinet manufacturing method. The method comprises the following steps that an aluminized zinc plate with a more than 2mm thickness is used, a multiple folding technology is used to make a shell of a switch cabinet, and a pulling rivet nut and a high-intensity bolt are used to carry out connection; a cover plate and a cabinet door which are made of metal are arranged on the shell, and the cabinet door of the switch cabinet and the shell are connected through a hinge; an internal portion of the switch cabinet is isolated into a cable terminal room, a mutual inductor room, a lightning arrester room and a cable room and observation windows are arranged, the observation windows of the mutual inductor room, the cable room and the lightning arrester room are infrared windows, a visual diameter of a lens of each infrared window is greater than or equal to more than 70mm, and an infrared transmittance is greater than or equal to 90%; a pressure relieve device is arranged, the pressure relieve device is closed under a normal condition, is opened when there is an accident and automatically release internal pressure; a cable wiring hole with a 120mm diameter is arranged on the cable room, a transverse steel angle supporting a cable head is arranged in the cable room and an upper portion of the steel angle is provided with a card hole. By using the method, an advantage of reducing an equipment failure rate is realized.
Description
Technical field
The present invention relates to field transformer, in particular it relates to a kind of 35kV withdraw-type switch cabinet manufacture method.
Background technology
At present, the scheduled overhaul system that in power system, power equipment uses mostly also exists major defect, and as frequent in provisional maintenance, maintenance deficiency or maintenance surplus, blindly maintenance etc., this makes countries in the world costly in terms of maintenance of equipment every year.And for a long time, China's power system performs periodic inspection system to power equipment, to equipment Inspection and maintenance, thus there is the drawback that maintenance is excessively not enough with maintenance in the most planned time cycle.Because of fault at power train unification, often cause large-area power failure.And there is the problem that fault rate is higher in existing power equipment.
Summary of the invention
It is an object of the invention to, for the problems referred to above, propose a kind of 35kV withdraw-type switch cabinet manufacture method, to realize the advantage reducing equipment failure rate.
For achieving the above object, the technical solution used in the present invention is:
A kind of 35kV withdraw-type switch cabinet manufacture method, including:
Use thickness 2mm above aluminizing zine plate, and use multiple seaming operation to make the shell of switch cubicle, and by blind nut and the bolt-connection of high intensity；
It is provided above with, at shell, cover plate and the cabinet door that metal is made, between cabinet door and the shell of switch cubicle, uses chain connection；
The internal insulation of switch cubicle is become CTC cable terminating cubicle, transformer room, spark gap room and cable vault, and all have observation window on the shell of CTC cable terminating cubicle, transformer room, spark gap room and cable vault, the observation window of transformer room, cable vault and spark gap room uses infrared window, the visual diameter of the eyeglass of described infrared window is more than or equal to more than 70mm, and infrared transmittivity is more than or equal to 90%；
Arranging pressure relief device in CTC cable terminating cubicle, transformer room, spark gap room and cable vault, pressure relief device is closed under normal circumstances, opens, be automatically releasable internal pressure under accident conditions；
Diameter 120mm cable connection hole is set in cable vault, and the horizontal angle steel supporting end is set in cable vault, and open hole clipping on angle steel top.
Preferably, described CTC cable terminating cubicle, transformer room, use non-magnetic corrosion resistant plate to isolate between spark gap room and cable vault.
Technical scheme has the advantages that
The present invention is by the improvement to 35kV withdraw-type switch cabinet processing technology, thus reduces the purpose of equipment failure rate.
Detailed description of the invention
A kind of 35kV withdraw-type switch cabinet manufacture method, comprises the following steps:

It is provided above with, at shell, cover plate and the cabinet door that metal is made, between cabinet door and the shell of switch cubicle, uses chain connection；
The internal insulation of switch cubicle is become CTC cable terminating cubicle, transformer room, spark gap room and cable vault, and all have observation window on the shell of CTC cable terminating cubicle, transformer room, spark gap room and cable vault, the observation window of transformer room, cable vault and spark gap room uses infrared window, the visual diameter of the eyeglass of described infrared window is more than or equal to more than 70mm, and infrared transmittivity is more than or equal to 90%；
Arranging pressure relief device in CTC cable terminating cubicle, transformer room, spark gap room and cable vault, pressure relief device is closed under normal circumstances, opens, be automatically releasable internal pressure under accident conditions；
Diameter 120mm cable connection hole is set in cable vault, and the horizontal angle steel supporting end is set in cable vault, and open hole clipping on angle steel top.
Preferably, described CTC cable terminating cubicle, transformer room, use non-magnetic corrosion resistant plate to isolate between spark gap room and cable vault.
Switch cabinet body size is particularly as follows: wide, deep and high be respectively 2018,3400 and 3700 (mm).The insulating barrier that the upper covering epoxy resin of corrosion resistant plate isolation, SMC or DMC material make.
Switch cubicle uses assembled armoured structure.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
