Description
Technical Field
The utility model belongs to the technical field of the transformer substation overhauls climbing equipment, a portable high altitude maintenance platform structure is related to.
Background
Two modes are generally adopted for installing a current transformer, a voltage transformer, a line YDR, an isolating switch and a lightning arrester of 35kV or more in a transformer substation.
The method is characterized in that a large crane is adopted for installation, the crane is huge in size, and the crane cannot enter and complete installation due to space limitation, traffic road limitation and other factors on some sites; the use cost of the crane is high; before installation, the crane needs to make appointment and wait with a crane leasing party in advance, and needs special crane personnel to operate, and the work is limited by the crane leasing party, so a large amount of time and financial resources are wasted in the whole equipment installation process, and the equipment is not comprehensively popularized and used (such as not configured in a county office).
And the second mode adopts a manual mode, and is mostly used under the condition that the space of the field is limited. However, the manual mode has too large physical load of personnel, and especially the site cannot provide safety guarantee conditions under the condition of strong physical labor of personnel, so the personnel are very unsafe.
Such as: when the isolating switch is maintained in a power transformation mode, the knife switch base is located right below the porcelain insulator; therefore, the porcelain bottle must be lifted up to carry out operations such as maintenance and the like. The manual dismantling of the existing porcelain insulator is almost impossible, and the manual dismantling device has great personal danger and labor intensity for operators. In addition, the conventional hoisting method of the crane has great defects. Firstly, according to the requirement of the safety distance, the effective safety distance can be ensured only by powering off the circuits around the isolating switch, so that the operation risk is increased, and meanwhile, the power failure of redundant circuits is also caused. Secondly, the crane is influenced by field equipment facilities, and all porcelain bottles on the same isolating switch are difficult to aim at the same position; moving and adjusting the crane position back and forth not only increases the overhaul time, but also increases the possibility of safety accidents.
