Detailed Description
The following describes in detail a box-type transformer with a temperature monitor for a low-voltage side circuit breaker according to the present invention with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, a box-type transformer with a low-voltage side circuit breaker including a temperature monitor comprises a box-type transformer case 5 with an opening at one bottom side, wherein the box-type transformer case 5 is provided with a low-voltage chamber circuit breaker 1 at the opening position, the rear end of the low-voltage chamber circuit breaker 1 is connected with an a-phase busbar 2, a B-phase busbar 3 and a C-phase busbar 4, the three wires are on the other side of the opening of the box-type transformer case 5 and are not easy to detect, the a-phase busbar 2, the B-phase busbar 3 and the C-phase busbar 4 are respectively connected with an HS-GQ300 fluorescent optical fiber temperature measurement system through three fluorescent temperature measurement wires 7, and the HS-GQ300 fluorescent optical fiber temperature measurement system respectively displays the real-time temperatures of the a-phase busbar 2, the B-phase busbar 3 and the C-phase busbar 4, and can realize timely temperature measurement display. When the temperature is abnormal or overhauled, the working personnel can find the temperature abnormality in time, and the potential safety hazard is reduced.
The other ends of the A-phase busbar 2, the B-phase busbar 3 and the C-phase busbar 4 are connected with a transformation box body 8, enter the transformation box body 8, then enter a high-voltage chamber 9 through transformation of a winding 10, and the system performs other working procedures.
The utility model relates to a low pressure side circuit breaker contains box transformer of temperature monitor's theory of operation is: because the box-type transformer is divided into a high-voltage chamber 9, a low-voltage chamber and a transformer, a breaker 1 and various electrical appliance measuring original devices are arranged in the low-voltage chamber, the breaker 1 in the low-voltage chamber passes through a box body of the low-voltage chamber through a three-phase busbar set to enter an oil tank and then is connected with the high-voltage chamber, the low-voltage chamber is often heated due to loose contact of the three-phase busbar set and moving and static contacts of the breaker 1 in the low-voltage chamber or due to long-time running vibration, because the low-voltage chamber is compactly installed, and the three-phase busbar set is arranged at the rear end of the breaker 1 in the low-voltage chamber, personnel cannot directly check or detect the three-phase busbar set during electrification, thus possibly causing fire hazard, the utility model monitors the temperature of the three-phase busbar set at the three-phase busbar set by additionally arranging a group of fluorescent temperature measuring wires 7, thereby improving the temperature rise, the efficiency that the fortune dimension personnel can in time handle through the temperature display body discovery temperature anomaly has reduced the possibility of taking place the conflagration because of the excess temperature, has improved factor of safety to a certain extent.
The utility model relates to a low pressure side circuit breaker contains temperature monitor's box transformer detects through female arranging, low voltage circuit breaker sound contact temperature to box transformer, has reduced the loss that equipment in time was not found to lead to because of the high temperature, has also improved equipment and staff's factor of safety.
