Embodiment 1
[0030] This embodiment provides a digital remote monitoring cabinet for cluster well group cathodic protection, including a cabinet body, an AC power control unit, a DC power control unit, an intelligent instrument monitoring unit, a DC shunt and a digital remote control terminal arranged in the cabinet , the AC power control unit, the DC power control unit and the DC shunt are electrically connected in sequence, the smart meter monitoring unit is electrically connected to the smart meter monitoring unit and the DC shunt, and the digital remote control terminal is connected to the smart meter monitoring unit in communication ;
[0031] The other end of the AC power control unit is connected to the AC power, one end of the DC shunt is connected to the negative pole of the DC power control unit, the other end is connected to the casing 12 of the oil-water well, and the positive pole of the DC power control unit is connected to the deep well anode 14 .
[0032] The present invent...
Embodiment 2
[0034] On the basis of embodiment 1, this embodiment provides a kind of figure 1 In the cluster well group cathodic protection digital remote monitoring cabinet shown, the AC power control unit includes a master control switch 1, an AC power indicator light 2, an AC integrated protector 11, a branch control switch 1 and a branch control switch 2 4. The main control switch 1, the AC power indicator light 2, and the integrated AC protector 11 are sequentially connected to the AC power supply, and the branch control switch 1 3 and the branch control switch 2 4 are connected to the AC power supply in parallel.
[0035] The industrial 220V voltage is grouped to the DC switching power supply for power supply, and the AC integrated protector 11 has the functions of leakage protection, lightning protection, short circuit protection and overload protection. When a lightning strike, leakage, short circuit, or overload fault occurs in the digital remote monitoring system, the AC integrat...
Embodiment 3
[0046] On the basis of Embodiment 2, this embodiment further describes the additional technical features of each constituent unit of the cathodic protection digital remote monitoring cabinet for cluster well groups.
[0047] The model of AC integrated protector 11 is G702-YJBH, which has comprehensive protection functions such as lightning protection, equipment leakage, circuit short circuit, and overload. When a lightning strike, equipment leakage, short circuit, or overload fault occurs, the AC integrated protector 11 will act instantaneously to cut off the AC power supply to protect the safety of the person and the DC switching power supply.
[0048] The DC power supply control unit includes a dual-circuit parallel adjustable switching power supply, which is composed of two 5KW independent adjustable switching power supplies connected in parallel. The positive pole of the power supply system is connected to the intelligent monitoring total ammeter 7, and then connected to t...
