Problems solved by technology

[0002] At present, the 500kV substation generally adopts a compact design, and the 35kV equipment area is close to the main transformer and adopts an open design, resulting in a narrow maintenance work space, and large hoisting equipment cannot be smoothly entered or deployed.
Moreover, the tight installation of the single-phase switch of the Siemens 3AP1FG circuit breaker determines that once the single-phase switch of the circuit breaker in the 35kV equipment area is damaged in this working environment, there is no suitable lifting tool for disassembly and replacement. Therefore, Bring great difficulty to maintenance work

preparation example Construction

[0033] The present invention also includes a method for preparing a fluorescent material containing aza-15-crown-5 cyclic crown ether, comprising the following steps:

[0034] Add the soluble salt of europium or terbium, L and organic solvent into the solvent heating jar, add 10~15ml of distilled water to seal, then put the sealed solvent heating jar into the muffle furnace; the soluble salt of europium or terbium, L The addition ratio of the organic solvent is 1 ~ 1.5mol: 1mol: 20 ~ 30ml; the organic solvent is xylene, cyclohexanol or DMF; the soluble salt of europium or terbium is nitrate or chloride; The structural formula of L is

[0035] , where R is H, -NO 2 ,-CHO;

[0036] First raise the temperature of the muffle furnace to 190~195°C for 48~72 hours, then lower the temperature of the muffle furnace to 50~55°C for 12~15 hours, turn off the power, and wait until the temperature of the muffle furnace drops to room temperature , the solvothermal jar was removed fr...

Abstract

The invention discloses a special hoisting tool for a breaker. A plurality of reinforcing ribs are evenly arranged between a steel pipe and a bottom plate. A base is arranged at the bottom. A winch is installed on the base. One end of a connecting rope of the winch is connected with the upper portion of the steel pipe. A hinge base is arranged on the bottom plate. The bottom plate is hinged to the steel pipe through the hinge base. A limiting block is arranged on the side, facing the winch, of the hinge base and matched with the steel pipe. The special hoisting tool is designed according to a 35 kV equipment area environment and the installation characteristics of a Siemens 3AP1FG series switch, and a single-phase switch of the Siemens 3AP1FG breaker can be hoisted in a narrow space. A cross rod is arranged on the steel pipe, a motor is installed on the cross rod, a base is arranged at the bottom of the motor, a positioning rod is formed in the base and matched with the cross rod, a pinion is installed on an output shaft of the motor, a big gear is installed on a fixing rod and engaged with the pinion, one side of the motor is provided with a pipe clamp, and the pipe clamp is fixed to the steel pipe. According to a manufacturing method, the defect that the yield is low when complex organic micromolecules are synthesized is overcome, and a solvothermal method is used for synthesis; and operation is simple, the special hoisting tool can be obtained easily, and the yield is high. The special hoisting tool for the breaker further has the advantages of being simple and compact in structure, low in manufacturing cost and easy and convenient to use.

Description

technical field [0001] The invention relates to a special hoisting tool, in particular to a special hoisting tool for a circuit breaker. Background technique [0002] At present, the 500kV substation generally adopts a compact design, and the 35kV equipment area is close to the main transformer and adopts an open design, resulting in a narrow maintenance work space, and large hoisting equipment cannot be smoothly entered or deployed. Moreover, the tight installation of the single-phase switch of the Siemens 3AP1FG circuit breaker determines that once the single-phase switch of the circuit breaker in the 35kV equipment area is damaged in this working environment, there is no suitable lifting tool for disassembly and replacement. Therefore, Bring great difficulty for maintenance work. Contents of the invention [0003] The purpose of the present invention is to provide a special hoisting tool for a circuit breaker, which is a special switch pendant made according to the ins...
