Abstract
The invention belongs to a telemetry system for the density in a cable branch joint sulfur hexafluoride air chamber, which is characterized in that: a data collection and collating unit uses RS-485 bus to be connected with at least an SF6 density monitor; the data collection and collating unit comprises a data collecting and storing processing unit, a power controlling unit, a key and display unit, a short message receiving / sending unit and a computer interface unit respectively connected with a central processing unit CPU; a GSM short message receiving / sending device is connected on the short message receiving / sending unit; an external power is connected on the power controlling unit. The telemetry system for the density in a cable branch joint sulfur hexafluoride air chamber has the advantages that: a solar energy battery is used as the power supply mode; short messages can be used for sending the monitoring situation of the density gauge two times each day; the density history record of one to two months can be provided for making copies on site and the cellphone number sending the short message can be changed; each line in the case is provided with an SF6 inflatable chamber with a total of three; the SF6 density in the three inflatable chambers can be monitored.
Description
technical field [0001] The invention belongs to a power supply device, in particular to a remote measurement system for the density of a sulfur hexafluoride gas chamber of a cable branch joint. Background technique [0002] The cable branch box is mainly used to connect cables. In order to ensure that the cable connection is always in a safe and reliable state, it is necessary to monitor the SF in the closed cable branch box at any time. 6 concentration. In the prior art, this detection work is mainly done manually. During operation, the staff members regularly use the detection device carried by the staff to carry out the detection. The defect of this detection method is that the operation is more troublesome. SF 6 The concentration control accuracy is relatively low. Contents of the invention [0003] The purpose of the present invention is to design a remote measurement system for the density of sulfur hexafluoride gas chamber at the cable branch joint, so as to facil...
