(Summary description)The busway involves problems such as loss of electrical energy, voltage drop on the equipment, and potential safety hazards. Therefore, the quality control of the busway is very important. At present, most of the projects only have three-phase four-wire or three-phase five-wire current. Some projects have increased the IP protection level. When designing the model, some important safety technologies should be clearly written on the drawings to prevent the latter due to technical parameters. Difficulties in construction settlement and reduction of security risks. Audit technical content: 1 current specification 2 protection grade IP 3 short-circuit withstand strength ICWKA4 ordinary busbar or fire-proof smoke extended busbar or fire-resistant busbar 5 temperature rise value 6 conductor interception capacity 7 protection circuit

Information

The busway involves problems such as loss of electrical energy, voltage drop on the equipment, and potential safety hazards. Therefore, the quality control of the busway is very important. At present, most of the projects only have three-phase four-wire or three-phase five-wire current. Some projects have increased the IP protection level. When designing the model, some important safety technologies should be clearly written on the drawings to prevent the latter due to technical parameters. Difficulties in construction settlement and reduction of security risks. Audit technical content: 1 current specification 2 protection grade IP 3 short-circuit withstand strength ICWKA4 ordinary busbar or fire-proof smoke extended busbar or fire-resistant busbar 5 temperature rise value 6 conductor interception capacity 7 protection circuit continuity, etc. If the above 7 technical data meet the technology Requirements, basically the certified products can be used with confidence. Quality control audit of production, inspection of conductors, whether the busbar conductor has an instrument for measuring the conductor resistivity, whether there is a voltage test equipment for the busbar, and whether there is a temperature rise test device for the interception capability of the busway, the protection circuit Continuous test equipment, which has a direct relationship with the passing rate of the products of the manufacturer. If these test equipments are available, the company's product quality assurance can provide an effective basis. Conductor auditing and testing, busbar conductor specifications have a 15-20% discount on the 40 °C ambient temperature current carrying capacity of the electrician's manual, and the busbar slot discount with poor heat dissipation is greater, such as the current carrying capacity of the busway. It is recommended to perform a temperature rise limit verification test when there is a gap.
