This utility model embodiment provides a kind of detecting device, as it is shown in figure 1, include:
For determining the processor 101 of zero line in equipment to be detected and ground wire whether wrong；It is connected with processor 101, for carrying out the first data acquisition unit 102 of data conversion；The fire-wire interfaces end 103 being connected with the live wire of equipment to be detected；The zero line interface end 104 being connected with the zero line of equipment to be detected；The interface of the ground wire end 105 being connected with the ground wire of equipment to be detected；With fire-wire interfaces end 103, interface of the ground wire end 105 and what the first data acquisition unit 102 connected respectively, for obtaining the first current transducer 106 of the current data of interface of the ground wire end 105；It is connected with fire-wire interfaces end 103, for the first power supply 107 of fire-wire interfaces end 103 power supply；It is connected with processor 101, is controlled by the State-output switch 108 of processor 101；With State-output switch 108, and be controlled by the first display lamp 109 and the second display lamp 110 of State-output switch 108.
It should be noted that under normal circumstances, the ground wire of Devices to test is user side ground connection, and the metal shell of Devices to test or human body can connect contact portion position, makes casing and the earth isoelectric level of Devices to test, and protection human body does not get an electric shock.And zero line in equipment to be detected and constitute electricity consumption loop between live wire, it is that equipment to be detected is powered by live wire, therefore, zero line and the live wire input voltage to equipment to be detected, there is electric current in this loop.
Concrete, the live wire of equipment to be detected, zero line and ground wire can be connected to the fire-wire interfaces end 103 of detecting device, zero line interface end 104 and interface of the ground wire end 105.Owing to the first current transducer 106 and interface of the ground wire end 105, fire-wire interfaces end 103, and the first data acquisition unit 102 connect.First power supply 107 is connected with fire-wire interfaces end 103, it is possible to provide power supply for fire-wire interfaces end 103.Now, if the zero line in equipment to be detected and ground wire do not have wrong, now, the live wire of equipment to be detected, when zero line and ground wire are connected to the fire-wire interfaces end 103 of detection equipment, zero line interface end 104 and interface of the ground wire end 105, owing to the fire-wire interfaces end 103 of detecting device is connected by the first current transducer 106 with interface of the ground wire end 105, therefore, fire-wire interfaces end 103 forms electric current by receiving the first power supply 107 and flows to interface of the ground wire end 105.Owing to interface of the ground wire end 105 is connected with the ground wire in equipment to be detected, when the ground wire of equipment to be detected does not have wrong with zero line, the ground wire of equipment to be detected is connected to ground, it is the first power supply 107 by fire-wire interfaces end 103, first current transducer 106 and interface of the ground wire end 105 are connected to ground, therefore, the first current transducer 106 do not have current data.
Current data in the first current transducer 106 that now the first data acquisition unit 102 gets is 0, and now current data can be 0 be converted to digital signal by the first data acquisition unit 102, and sends to processor 101.The current data of the first data acquisition unit 102 transmission that processor 101 receives is 0, and now processor 101 can know that the ground wire of equipment to be detected and zero line do not have wrong.Processor 101 is connected with State-output switch 108, and the first display lamp 109 and the second display lamp 110 are connected with State-output switch 108, and therefore, processor 101 can send the first instruction to State-output switch 108.After State-output switch 108 receives the first instruction, it is possible to control the light on and off of the first display lamp 109 and the second display lamp 110 according to the first instruction, in order to inform that the ground wire of user's equipment to be detected and zero line do not have wrong.
It should be noted that the first instruction is for indicating when the ground wire of user's equipment to be detected does not have wrong with zero line, the light on and off situation of the first display lamp and the second display lamp.Can be configured according to user's actual need.It is and can preset the light on and off situation that the first display lamp and the second display lamp are set, inform that the ground wire of user's equipment to be detected and zero line do not have wrong.Such as, bright at the first display lamp, when second display lamp goes out, the ground wire indicating equipment to be detected does not have wrong with zero line, then when the ground wire that equipment to be detected determined by processor does not have wrong with zero line, instruction the first display lamp can be sent bright, the first instruction that the second display lamp goes out to State-output switch.Now, after State-output switch receives the first instruction, it is possible to controlling the first display lamp according to the first instruction bright, the second display lamp goes out.Certainly, the first instruction can also is that other situations of the light on and off of the first display lamp and the second display lamp.This utility model is without limitation.
And when ground wire and the zero line wrong of equipment to be detected, the zero line interface end 104 being detecting device is connected as the ground wire of equipment to be detected, and interface of the ground wire end 105 connects is the zero line of equipment to be detected.Therefore, when fire-wire interfaces end 103 forms electric current by receiving the first power supply 107 and flows to interface of the ground wire end 105, owing to interface of the ground wire end 105 is connected with the zero line in equipment to be detected, and loop can be formed between the live wire of equipment to be detected and zero line, therefore the first power supply 107 can provide power supply for loop between the live wire of equipment to be detected and zero line, so that have electric current between fire-wire interfaces end 103 and interface of the ground wire end 105, therefore the first current transducer 106 can get current data.Owing to the first current transducer 106 is also connected with the first data acquisition unit 102, therefore, the first data acquisition unit 102 can receive the current data of the first current transducer 106 transmission.Owing to the current data of the first current transducer 106 transmission is analogue signal, and processor 101 only can recognise that digital signal, therefore the current data of the analogue signal of reception can be converted to the current data of digital signal by the first data acquisition unit 102, and the current data of digital signal is transmitted to connected processor 101.After now processor 101 receives current data, detecting that current data is the numerical value more than 0, processor 101 can determine that ground wire and the zero line wrong of equipment to be detected.So, processor 101 needs the ground wire informing user's equipment to be detected and zero line wrong.Therefore, processor 101 is connected with State-output switch 108, first display lamp 109 and the second display lamp 110 are connected with State-output switch 108, so, processor 101 can send the second instruction to State-output switch 108, after State-output switch 108 receives the second instruction, it is possible to control the light on and off of the first display lamp 109 and the second display lamp 110 according to the second instruction, in order to inform ground wire and the zero line wrong of user's equipment to be detected.
It should be noted that the second instruction is for indicating when the ground wire of user's equipment to be detected is with zero line wrong, the light on and off situation of the first display lamp and the second display lamp.Can be configured according to user's actual need.It is and can preset the light on and off situation that the first display lamp and the second display lamp are set, inform ground wire and the zero line wrong of user's equipment to be detected.Such as, go out at the first display lamp, when the second display lamp is bright, indicate ground wire and the zero line wrong of equipment to be detected, then when processor determines the ground wire of equipment to be detected with zero line wrong, it is possible to send instruction the first display lamp to State-output switch and go out, the second instruction that the second display lamp is bright.Now, after State-output switch receives the second instruction, it is possible to controlling the first display lamp according to the second instruction and go out, the second display lamp is bright.Certainly, the second instruction can also is that other situations of the light on and off of the first display lamp and the second display lamp.This utility model is without limitation.
So, detecting device can pass through the live wire of fire-wire interfaces end, zero line interface end and interface of the ground wire end and equipment to be detected, zero line and ground wire connection.And by the current data of the first current transducer locality line interface end, and then by the first data acquisition unit, this current data carried out data conversion, and by the data transmission of conversion to processor.Processor can determine zero line in equipment to be detected and ground wire whether wrong according to the data received, and then the first display lamp and the light on and off of the second display lamp can be controlled by filling output switch, to inform manager's equipment to be detected whether zero line and ground wire wrong.Such that it is able to when the ground wire of equipment and zero line wrong, it is possible to detected timely by detecting device, add the completeness of terminal unit.
Further, as in figure 2 it is shown, the first current transducer 106 of above-mentioned detection device is connected with zero line interface 104 end.
Concrete, the first current transducer 106 and fire-wire interfaces 103, zero line interface 104, interface of the ground wire 105 and the first data acquisition unit 102 connect.So, when the live wire of equipment to be detected and zero line wrong, it can also be ensured that detection equipment can carry out the detection of the ground wire of equipment to be detected and zero line whether wrong normally.Wherein, the detection process that detection equipment carries out the ground wire of equipment to be detected and zero line whether wrong is identical with above-mentioned detection process, does not repeat them here.
By said process, detecting device can be avoided, when the live wire of equipment to be detected is with zero line wrong, the situation of live wire with ground wire wrong being occurred.It is, in equipment to be detected, zero line is regarded live wire by mistake, zero line regarded by ground wire, when live wire is as ground wire, the ground wire of equipment to be detected and the situation of zero line wrong can be detected due to detecting device, thus avoiding the shell that live wire is connected to equipment to be detected as ground wire, the situation of security incident occurs.Further increase the completeness of terminal unit.
Further, above-mentioned detection device, as it is shown on figure 3, also include:
Respectively with fire-wire interfaces end 103, zero line interface end 104 connects, for obtaining the second current transducer 111 of the current data of fire-wire interfaces end 103；With the second current transducer 111 and what processor 101 was connected, for carrying out the second data acquisition unit 112 of data conversion.
Respectively with fire-wire interfaces end 103, zero line interface end 104 connects, for obtaining the 3rd current transducer 113 of the current data of zero line interface end 104；With the 3rd current transducer 113 and what processor 101 was connected, for carrying out the 3rd data acquisition unit 114 of data conversion.
Concrete, in detecting device, it is respectively provided with current transducer for fire-wire interfaces end 103, zero line interface end 104 and interface of the ground wire end end 105.So, processor 101 in detecting device can pass through the second power pack 111 and obtain the current data of fire-wire interfaces end 103, the current data of zero line interface end 104 is obtained by the 3rd power pack 113, the current data of zero line interface end 105 is obtained by the first power pack 102, and then the live wire of spot check measurement equipment can be known, zero line, ground wire whether wrong.
When the live wire of equipment to be detected, zero line and ground wire all do not have wrong, the live wire of equipment to be detected, zero line and ground wire connect with the fire-wire interfaces end 103 of detecting device, zero line interface end 104 and interface of the ground wire end 105 respectively.Owing to the live wire of equipment to be detected, zero line and ground wire all do not have wrong, therefore, loop between the live wire of equipment to be detected and zero line, can be formed, be this loop power supply by the first power supply 107, so, the loop between live wire and zero line has electric current to be formed.So, the second current transducer 111 can collect the first current data, and the 3rd current transducer 113 can collect the second current data.Ground wire grounded due to equipment to be detected, does not therefore have electric current on the circuit at interface of the ground wire end 105 place, and so, the current data that the first current transducer 106 collects is 0.Owing to the first current transducer 106 is connected with the first data acquisition unit 102, second current transducer 111 is connected with the second data acquisition unit 112,3rd current transducer 113 is connected with the 3rd data acquisition unit 114, therefore, the current data that the current data of collection is 0 can be sent to the first data acquisition unit 102 by the first current transducer 106.The first current data gathered can be sent to the second data acquisition unit 112 by the second current transducer 111.The second current data gathered can be sent to the 3rd data acquisition unit 114 by the 3rd current transducer 113.Due to the first data acquisition unit 102, the second data acquisition unit 112 and the 3rd data acquisition unit 114 are all connected with processor 101.The data being capable of identify that due to processor 101 are digital signal, and the first data acquisition unit 102, the signal that second data acquisition unit 112 and the 3rd data acquisition unit 114 obtain is analogue signal, therefore the first data acquisition unit 102, second data acquisition unit 112 and the 3rd data acquisition unit 114 need existing by analogue signal, the current data of acquisition to be converted to digital signal, and being the first data acquisition unit 102, the analogue signal that current data is 0 is converted to the current data of digital signal is 0.First current data is converted to the first current data of digital signal by the second data acquisition unit 112 by analogue signal.Second current data is converted to the second current data of digital signal by the 3rd data acquisition unit 114 by analogue signal.The current data of digital signal is 0 transmission to processor 101 by the first data acquisition unit 102, first current data of digital signal is sent to processor 101 by the second data acquisition unit 112, and the second current data of digital signal is sent to processor 101 by the 3rd data acquisition unit 114.Processor 101 receives the first data acquisition unit 102, second data acquisition unit 112, after the current data that 3rd data acquisition unit 114 sends, through resolving, determine the live wire of equipment to be detected, the all non-wrong of zero line and ground wire, now processor 101 can send to the first instruction to State-output switch 108, State-output switch 108 can according to the first instruction, control the light on and off of the first display lamp 109 and the second display lamp 110, to inform all non-wrong of the live wire of user's equipment to be detected, zero line and ground wire.
Wherein, how State-output switch 108 is according to the first instruction, and the light on and off controlling the first display lamp 109 and the second display lamp 110 are referred to said process, and this utility model does not repeat them here.
It should be noted that processor can be informed in the live wire of equipment to be detected by experiment in advance, zero line, during ground wire all non-wrongs, the live wire current data scope that electric current on live wire is corresponding, and the first current data is within the scope of live wire current data.The neutral line current scope of data that electric current on zero line is corresponding, and the second current data is in neutral line current scope of data.
