Fireproof poured bus way

Abstract

The invention relates to a fireproof poured bus way which is capable of overcoming the shortages that a low-voltage power transmission and distribution bus way main line system can not be used outdoors and in the environment with corrosion pollution. The fireproof poured bus way can be safely operated for a certain time under the state of a fire disaster. According to the fireproof poured bus way, the method of 'processing technology of pressure injection gel forming epoxy poured bus way' (patent application number: 201220081075.3) is adopted, fireproof agent, filling agent and curing agent are added into inflaming retarding epoxy resin, wherein the fireproof agent, the filling agent and the curing agent are in an appropriate matching ratio, the fireproof agent, the filling agent, the curing agent and the inflaming retarding epoxy resin are stirred in a vacuum stirring machine when the vacuum stirring machine is vacuum-pumped, the completely mixed mixture is injected into a pre-heated steel die through pressure, so that thermal-curing gel forming is conducted, and fireproof poured bus units are formed. After the fireproof poured bus units are firmly connected through mica insulation joint connectors researched and developed by this company according to the engineering design requirements, the fireproof poured bus units are sleeved with a 'connecting box for poured bus way' (patent application number: ZL 201020104497.9), and a fireproof pouring mixed material is poured along a pouring notch of the connecting box so that the whole fireproof poured bus way can be cured.

Description

1. Technical field [0001] The patent of the present invention "refractory cast busway" relates to the technical field of the fire resistance performance of the energized casted busway which can be insulated safely and continuously energized for a certain period of time in a fire state. 2. Background technology [0002] With the improvement of people's living standards, the world's population is increasing day by day, the scarcity of land resources, the pollution of the environment and climate, the towering of high-rise buildings, and the frequent occurrence of various fire accidents have made people increasingly aware of their own safety and fire prevention. [0003] At present, the traditional steel refractory bus duct adopts the method of wrapping mica tape (mica partition) and filling aluminum silicate wool and other refractory materials outside, so that the steel refractory bus duct can be safely energized and run for a certain period of time in the event of a fire.

Problems solved by technology

[0008] In order to overcome the shortcomings of the traditional double-layer structure of steel refractory busway, such as large volume, high cost, waste of resources, and inability to be used in the open air and in environments with corrosion pollution, the present invention adopts "pressure injection gel molding epoxy casting The processing technology of bus duct" method (patent application number: 201220081075.3), after adding an appropriate amount of fire retardant, filler and curing agent to the flame retardant epoxy resin, the fully mixed product is stirred in a vacuum mixer while vacuuming The mixture is injected into the preheated steel mold with pressure to form the refractory castable busbar unit by thermosetting gel. After the refractory castable busbar unit is firmly connected through the mica insulated joint connector designed and developed by our company according to the engineering design requirements, "Joint Box for Casting Busway" (Patent No.: ZL201020104497.9) dedicated for outer jacket, pouring refractory pouring mixture along the pouring notch of the joint box to solidify it into a whole refractory castable busway
