In the embodiment of the present application, the primary side of the electrical signal transformer 101 is connected to the power grid 500, and the load current includes the current transmitted from the power grid 500 to the primary side of the electrical signal transformer 101. Wherein the electrical signal transformer 101 may include at least one of a current transformer and a voltage transformer.
The control assembly 200 is coupled to each of the electrical signal detection assemblies 102 for determining each of the target neutral wires having a neutral wire current greater than a preset first threshold, wherein the target neutral wire is the multipoint-grounded neutral wire 103.
In application, when the primary side of the electrical signal transformer 101 transmits the load current, the neutral wire 103 on the secondary side of the electrical signal transformer 101 in each terminal box 100 transmits the neutral wire current, and since each electrical signal detection component 102 is correspondingly connected with the neutral wire 103 on the secondary side of the electrical signal transformer 101 in each terminal box 100, each electrical signal detection component 102 can detect the neutral wire current transmitted by each neutral wire 103, while the control component 200 is connected with each electrical signal detection component 102, the control component 200 can receive the neutral wire current detected by each electrical signal detection component 102, the control component 200 can compare each acquired neutral wire current with a preset first threshold value to determine each target neutral wire with the neutral wire current larger than the preset first threshold value, and each target neutral wire is a neutral wire grounded in a multipoint manner, therefore, the neutral wire grounded in a multipoint manner and each abnormal terminal box where the target neutral wire is located can be detected in time, and then the multipoint grounding condition in each abnormal terminal box in the transformer substation can be reported in time, so that related technicians find hidden danger of safety equipment in the transformer substation can be guaranteed in time.
According to the transformer substation terminal box monitoring device, the electric signal detection assemblies are respectively and correspondingly connected with the neutral wires of the secondary sides of the electric signal transformers in the terminal boxes, the electric signal detection assemblies can detect neutral wire currents transmitted by the neutral wires, the control assemblies are connected with the electric signal detection assemblies, the control assemblies can determine the target neutral wires with the neutral wire currents larger than the preset first threshold value, and the target neutral wires are grounded by multiple points, so that the neutral wires grounded by multiple points and the abnormal terminal boxes where the target neutral wires are located can be timely detected, and then the multi-point grounding conditions in the abnormal terminal boxes in the transformer substation can be timely reported, so that related technicians can timely find potential safety hazards, and the safety of a power grid and equipment in the terminal boxes is guaranteed.
In one embodiment, as shown in fig. 1, each electrical signal detecting assembly 102 is further correspondingly connected to a phase line 104 on the secondary side of the electrical signal transformer 101 in each terminal box 100, and is used for collecting phase currents transmitted on the phase line 104 in each terminal box 100.
The control assembly 200 is further configured to obtain each candidate neutral line with a neutral line current less than a preset second threshold value, and determine an abnormal neutral line with a broken line from the candidate neutral lines, where a phase current of the phase line 104 located in the same terminal box as the abnormal neutral line is greater than a preset third threshold value, and the second threshold value is less than the first threshold value.
It is understood that when the electrical signal transformer 101 is in the normal operation state, the secondary side neutral line current of the electrical signal transformer 101 fluctuates within a preset second threshold value to a first threshold value. The fact that the electric signal transformer 101 is in a normal operation state means that the primary side of the electric signal transformer 101 is connected to the power grid 500 and load current flows. The electrical signal detection component 102 is configured to detect a secondary side neutral current of the electrical signal transformer 101, and feed back detected neutral current information to the control component 200, where the control component 200 may obtain a candidate neutral line of the secondary side neutral current of the electrical signal transformer 101 that is less than a preset second threshold; meanwhile, each electric signal detection assembly 102 is correspondingly connected with the phase line 104 of the secondary side of the electric signal transformer 101 in each terminal box 100 respectively, so as to collect the phase current transmitted on the phase line 104 of the secondary side of the electric signal transformer 101 in each terminal box 100. The control component 200 may obtain the phase line on the secondary side of the same electrical signal transformer 101 as each candidate neutral line, and obtain the phase line current, so as to determine, from each candidate neutral line, an abnormal neutral line on the secondary side of the same electrical signal transformer 101 with the phase line 104 having a phase current greater than a preset third threshold value, where the abnormal neutral line is a neutral line of a broken line, so that the broken neutral line may be detected in time.
In application, the electric signal detection component 102 may include a first current sensor and a second current sensor, where the first current sensor is connected to the neutral line 103 on the secondary side of the electric signal transformer 101, and is used to detect the current information of the neutral line on the secondary side of the electric signal transformer 101; the second current sensor is connected with the phase line 104 of the secondary side of the electric signal transformer 101 and is used for detecting the phase line current information of the secondary side of the electric signal transformer 101. The control assembly 200 is connected to the first current sensor and the second current sensor, respectively, and is configured to receive neutral current information and phase current information detected by the first current sensor and the second current sensor.
Illustratively, the electrical signal detection assembly 102 of the first terminal box detects a first neutral current on the secondary side of the first electrical signal transformer in the first terminal box and feeds back first neutral current information to the control assembly 200; the electric signal detection assembly 102 in the second terminal box detects a second neutral current of the secondary side of the second electric signal transformer in the second terminal box and feeds back the detected second neutral current information to the control assembly 200. Wherein, if the first neutral line current and the second neutral line current are both less than the preset second threshold value, the control component 200 may determine the corresponding first neutral line and second neutral line as candidate neutral lines; the electric signal detection component 102 in the first terminal box detects the first phase line current of the secondary side of the first electric signal transformer of the first terminal box again, and feeds back the detected first phase line current information to the control component 200; the electric signal detection assembly 102 in the second terminal box again detects the second phase line current of the secondary side of the second electric signal transformer in the second terminal box, and feeds back the detected second phase line current information to the control assembly 200. If the first phase current is greater than the preset third threshold value and the second phase current is less than the preset third threshold value, the control component 200 may determine a first neutral line located on the secondary side of the first electrical signal transformer and the first phase line from the candidate neutral lines, and determine the first neutral line as an abnormal neutral line.
In this embodiment, the electrical signal detection component 102 detects the current information of the secondary side neutral wire of the electrical signal transformer 101 and feeds back the current information to the control component 200, so that the control component 200 obtains a candidate neutral wire with a neutral wire current smaller than a preset second threshold value, and then the electrical signal detection component 102 detects the current information of the secondary side phase wire of the electrical signal transformer 101 and feeds back the current information to the control component 200, so that the control component 200 determines an abnormal neutral wire which is located on the secondary side of the same electrical signal transformer 101 with a phase wire current larger than a preset third threshold value from the candidate neutral wires. Therefore, various abnormal terminal boxes with neutral line disconnection conditions in the transformer substation are detected in time, and related technicians can find potential safety hazards in time, so that safety of equipment in the power grid and the terminal boxes is guaranteed.
In one embodiment, as shown in fig. 2, the substation terminal box monitoring device further comprises at least one thermal imaging assembly 105.
The thermal imaging assemblies 105 are respectively arranged in the terminal boxes 100 and are used for acquiring thermal images of the current terminals in the terminal boxes 100. Wherein the thermal imaging assembly 105 includes, but is not limited to, an infrared camera.
The control unit 200 is connected to each thermal imaging unit 105, and is configured to acquire thermal images of each current terminal in each terminal box 100, and determine an abnormal current terminal based on the thermal images of each current terminal.
