· # ZW43-12 / 630-20 ￥% ￥ ZW43-12 / 1250-25 Outdoor high voltage vacuum circuit breaker I. Overview 1.1 $ Type and ZW43-12 / 630-20 outdoor high-voltage vacuum circuit breakers. 1.2 # ￥ The main purpose ZW43-12 / 630-20 outdoor high-voltage vacuum circuit breaker (hereinafter referred to as breaker) rated voltage 12KV, three-phase AC 50Hz outdoor distribution equipment. Mainly used for breaking, closing power system load current, overload current and short circuit current. For substation and industrial and mining enterprises in the power distribution system of workplace protection and control purposes, and rural power grids frequent operation. This installation manual provides the main technical parameters of the circuit breaker, the product mix, as well as the principles and methods of operation, installation, use and maintenance of content. Model significance 1.3 $ 1.4 Reference standard circuit breaker in line with "GB / T11022 high-voltage switchgear and control equipment standards common technical conditions", "GB1984-89 AC circuit breaker" "GB1985-89 High voltage isolating switches and earthing switches" and DL404, and other relevant requirements of IEC56 standards. 1.5 Use of environmental conditions 1, altitude of not more than 2000 m; 2, ambient air temperature: -45 ℃ ~ + 65 ℃; diurnal temperature: the diurnal variation of 25 ℃; 3, the wind speed is not greater than 35m / s; 4, non-flammable, risk of explosion, chemical corrosion and severe vibration. The main technical parameters of 1.6% and stable high-voltage vacuum circuit breaker (see Table 1) 2.2 to arc chamber equipped with a vacuum breaking performance and reliable, with no fire and explosion hazards, safety, maintenance-free, small size, light weight (<100kg) and long service life. 2.3 breaker fully enclosed structure, good sealing performance, moisture-proof, anti-condensation properties, adapted for use in hot and humid regions. Closing and opening the circuit breaker 2.4 can be manually or electrically operated and remote operation. With controller supporting realize distribution automation, but also coincides with the composition of recloser controllers. 2.5 Operating mechanism is novel, simple, reliable operation, small size, mechanical life of up to 10,000 times. 2.6 installation can be single pole breaker or double pole base loading mode. 3, $ installation, use and maintenance 3.1 column breaker box should be checked for damage insulation cover, nameplate, certification is consistent with the physical. 3.2 breaker put into operation before the column, should carefully check the rated voltage of each of the operating element, the rated current is consistent with the actual situation. And trial operation with institutions having sub-gate way to check the indicators are correct. 3.3 Breaker can be divided into single poles, can also double poles (as two, three, four, five below). 3.4 column breaker because of its special design of the structure to ensure that users in the use of long-term maintenance. 3.5 users can not replace the use of model specifications are inconsistent with the original electrical components. 3.6 The operator should adjust the preliminary understanding of performance and installation mechanism, maintaining knowledge of operational problems should be recorded, can inform the manufacturer if necessary. 4, $ transportation, acceptance and storage 4.1 Transport Transport must load the entire station to be fixed in a closed box. During transport must not flip, tilt, shock measures to be taken. After receiving the acceptance column breaker 4.2 users should perform the following tasks: 1, check whether the packaging is damaged 2, control and packing list to check whether a file is complete, accessories and spare parts are complete. 3, the technical parameters of the column circuit breaker nameplate inspection, product certification meets the requirements of orders. 4.3 Storage This column breaker should be stored in dry, ventilated, moisture-proof, shock-proof and anti-harmful gas attack in indoor, long-term storage environment should be regularly checked for compliance. Packing, unpacking and storage should be in a dry room, the product should be checked and the parts are complete and consistent. 5. Ordering Information should be $ 5.1 ordering the product model (for example, circuit breakers rated breaking capacity, whether the circuit breaker with isolation switch, circuit breaker or without current transformer and the number of auxiliary power mode, etc.), the name, number and the necessary current transformer ratio. 5.2 User shall propose installation, select the appropriate fastening accessories. 5.3 user must select the appropriate function configured according to the requirements. 7.1 When handling the switch, non Taikang pile into the outlet and current transformers for damage resulting neither belong to product quality. 7.2 Any situation allowed close to the insulating cover loose brass nut (marked with red paint).
