Problems solved by technology
This method is more suitable for ring network cabinets with relatively large unit intervals, and the cost is relatively low. However, for some RM6 gas ring network cabinets, due to the relatively small intervals, if T-shaped forward sockets have been installed, then connect into the auxiliary device, there is not enough space to complete the actual operation

The invention discloses a ring main unit emergency power supply rapid access device and an automatic temperature sensing detection method. The T-shaped front plug is used for a ring main unit with a standby unit, the T-shaped rear plug is used for a ring main unit without a standby unit, each of the T-shaped front plug and the T-shaped rear plug comprises a T-shaped metal shell, a conductive red copper tube, insulating silicon rubber, a high-voltage grading ring, a wireless temperature sensing device and an inward-retracting rotary type fixing seat, and the conductive red copper tube is mounted in the T-shaped metal shell; the insulating silicone rubber wraps the outer side of the conductive red copper tube and is arranged in the T-shaped metal shell, the high-voltage grading ring, the wireless temperature sensing device and the inward-retracting rotary type fixing seat are all installed at the lower end of the T-shaped metal shell, and the wireless temperature sensing device is arranged between the high-voltage grading ring and the inward-retracting rotary type fixing seat. The invention has the following beneficial effects: two different operation conditions are compatible; the creepage influence is completely eradicated; electrical full isolation increases the contact area and reduces the heating influence; the electromagnetic influence is reduced; operation safety is improved, and personnel risks are reduced.
Description
technical field [0001] The invention relates to the related technical field of pressure bypass without power failure operation, in particular to a rapid access device for emergency power supply of a ring network cabinet and an automatic temperature sensing detection method. Background technique [0002] Live distribution network operation is an important measure for international advanced power grid enterprises to improve the reliability of power supply. It plays an important role in reducing pre-arranged power outage time and frequency, and improving customer experience in power consumption. However, conventional distribution network live work is generally carried out when the distribution line is not under load, requiring small-scale power outages, and cannot achieve uninterrupted power supply to customers, which affects the service quality of power grid enterprises to customers to a certain extent. In order to reduce customer outage time and improve the lean management le...
