Technical Field
The utility model relates to a power equipment technical field especially relates to an auxiliary bolt of locking of mechanism case.
Background
At present, the disconnecting link of 35kV or more of a transformer substation is mostly provided with an electric operating mechanism. In order to prevent other disconnecting switches from being operated by mistake due to wrong intervals in actual operation, the Guangdong power grid company requires that a motor power supply of the electric disconnecting switch is in a disconnected state in the normal operation process. Therefore, the knife switch mechanism box is locked by a mechanical lock in normal operation, so that on one hand, the risk of misoperation of the knife switch caused by the fact that a worker mistakenly throws a power supply of a knife switch motor is prevented; on the other hand, the device can prevent the device from being damaged due to the fact that a worker randomly opens the box door of the mechanism and mistakenly touches the operating device. When the knife switch needs to be electrically operated, the mechanical lock is unlocked by using a simulated microcomputer five-prevention computer key, then the motor power supply needing to operate the knife switch is switched on for operation, the motor power supply is immediately disconnected after the operation is finished, and then the mechanical lock is locked again.
However, some manufacturers have no padable areas for the knife gate mechanism box body (such as the siemens manufacturer), so that mechanical locks cannot be used to lock this type of mechanism box. The risk of personal and power grid accidents caused by the fact that the switch-on switch is pulled by mistake in the operation process due to the fact that the power supply of the switch-on switch motor is switched on by mistake in normal operation can be greatly increased; in the maintenance construction process, a worker can freely switch on and off a motor power supply in the disconnecting link mechanism, safety measures are changed at will, and the risk of mistakenly switching on and switching off the disconnecting link and electric shock of a human body is increased; the staff easily opens the mechanism chamber door at will and bumps the operation equipment by mistake and causes the equipment damage.
