Background technique
The inflatable cabinet is a new generation of switchgear. The whole cabinet adopts the combination of the air insulation of the mechanism room and the sulfur hexafluoride gas compartment of the switch room, which is compact and expandable, and is suitable for power distribution automation. The inflatable cabinet has the characteristics of compact structure, flexible operation and reliable interlocking. The current inflatable cabinet has the problem of short service life when in use. The mechanical life test of the outlet mechanism of the SF6 inflatable cabinet load switch on the market generally cannot meet the requirements of the State Grid.
Technical realization elements
The purpose of the utility model is to solve the defects existing in the prior art and provide an outlet mechanism for the load switch of the inflatable cabinet.
In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is:
An outlet mechanism for a load switch of an inflatable cabinet includes a front plate and a rear plate that are parallel to each other. A hexagonal shaft and a positioning shaft are connected between the front plate and the rear plate. A shaft sleeve is sleeved on the hexagonal shaft. The main shaft, the grounding shaft and the closing operation shaft, the upper and lower sides of the main shaft are connected with connecting rods, the upper connecting rod is connected with the upper fork plate, the lower connecting rod is connected with the lower fork plate, the upper fork plate and the lower fork plate Connect the hexagonal shaft;
A motor is fixed on the rear plate, the output shaft of the motor is connected to a reduction gear box, the output end of the reduction gear box is connected to an auxiliary cam, and the auxiliary cam is sleeved on the main shaft;
An energy storage micro switch is installed on the rear panel, an energy storage limit plate is installed on one side of the energy storage micro switch, and one side of the energy storage limit plate is connected to a movable swing arm. The movable swing arm is connected to the energy storage micro switch. Hinged on one side;
One side of the energy storage limiting plate is provided with a gate opening plate, the side of the gate opening plate is provided with an electromagnet, and the end of the electromagnet corresponds to the gate opening plate.
The spring operating mechanism cannot store energy
The main reasons for the failure are
1. Malfunction of the motor power supply and its circuit
(1) The power circuit is broken or the fuse is blown.
(2) Although the power switch of the motor is closed, the main switch of the circuit is not turned on.
(3) The auxiliary component of the secondary control loop fails, so that the power supply is not connected.
2. The motor itself is faulty
(1) The mechanical part of the energy storage is jammed.
(2) Motor burns.
(3) The winding is broken or short-circuited.
(4) If it is a DC motor, the commutator or carbon brush may be faulty.
