[specific embodiment]
It please referring to shown in Figure of description 1 and 2, the present invention is portable high-pressure direct current cabinet PDU socket detector, including
There are three hole connectors 1, two branches are parallel on three hole connectors 1, a branch road has been sequentially connected in series protection location 2, voltage detecting
Unit 3, comparison unit 4, display unit 5, LED light 6.Other branch road is in series with short detection unit 7, power supply unit 8,
And short detection unit 7 is also connected on display unit 5 simultaneously.
Three hole connectors 1 are to receive circuit voltage signal for being inserted into detected high voltage direct current PDU socket.Protection is single
Member 2 is used to protect entire detection device, when there is voltage surge in system or input direct-current voltage is more than DC290V, protection location
2 play disconnection measure, while circuit being protected to prevent over-voltage bring failure risk.In order to make whole device more safe and reliable,
Protection fuse 9 can also be added in the present embodiment, and protection fuse 9 is to be concatenated into three hole connectors 1 and protection on circuit position
Between unit 2, mainly there is accidental short circuit when high voltage direct current detector itself breaks down or in test process in protection fuse 9
Phenomenon, electric current are more than 3A, and protection fuse fuses rapidly, so that the high voltage direct current detector of failure is detached from from system, are avoided
Harm is brought to system.
Voltage detection unit 3 predominantly detects the voltage of high voltage direct current PDU socket, and comparison unit 4 is mainly positive and negative by comparing
The difference of pole (PE) voltage over the ground.The voltage that voltage detection unit 3 detects is mainly this three: PE (on three hole connectors) and positive grade
Voltage, positive grade (three hole connectors between voltage, PE (on three hole connectors) and cathode (a three hole connectors left side) between (three hole connectors right)
It is right) with voltage between cathode (a three hole connectors left side).Comparison unit 4 will test three reading data that unit 3 detected, and right
PE voltage and cathode are compared between PE voltage three for voltage, the anode of positive and negative anodes, judge the state of system line.
Display unit 5 and LED light 6 are mainly used for shows system voltage value and positive and negative anodes voltage-to-ground value.Referring to Fig. 1, show
Show that unit 5 can be display screen form, layout is various LED light 6 in the positive top of product, lower section, specifically there is line status
Lamp, line sequence lamp, earth lamp, positive suspension lamp, cathode suspension lamp.
Three hole connectors 1 while short detection unit 7, power supply unit 8.Short detection unit 7 is used for non-live high voltage direct current
PDU socket power on before short-circuit detecting, power supply unit 8 mainly to short detection unit 7 power.Short detection unit 7 simultaneously
It is connected on display unit 5 and shows.It when short detection unit 7 needs to start, needs to start switch, therefore is set on product front
Set short-circuit test button.Short detection unit 7 could be enabled to start work after button is pressed.
It is three hole connectors 1 in the back side of product, lower section is protection fuse 9, when protection fuse 9 is if necessary to replace,
Just directly replaced on panel.
Utility model works principle is as follows:
Short-circuit detecting before power transmission
1, phase fault and shorted to earth measurement: for the PDU that does not power on or will power on using the utility model into
When row detection, it is inserted into the socket to be detected and presses short-circuit test button, power supply unit 8 is powered short detection unit 7,
Short detection unit 7 determines whether short-circuit condition, and in LED light 6 by measuring to positive and negative circuit and to earth-return
Line status lamp shows (normal green instruction or red short circuit alarm instruction).
It is tested after power transmission
1, three hole connectors 1, which are aligned, is detected high voltage direct current PDU socket, through overprotection fuse 9 and the dual guarantor of protection location 2
Shield, it is ensured that work normally detection.
2, voltage detection unit 3 predominantly detects the voltage of high voltage direct current PDU socket, and high voltage direct current total voltage can directly exist
Directly displayed in display unit 5, and reflecting voltage fluctuation in real time and it is normal whether.
3, comparison unit 4 is fetched from detection unit 3, when the detection of PE (on three hole connectors) and positive (three hole connectors are right)
Voltage is that positive value, PE and negative (three hole connectors are left) voltage are negative value, and contrast circuit is shown in green by line sequence lamp, indicates line sequence symbol
Close national standard.When the detection voltage of PE (on three hole connectors) and positive (three hole connectors are right) is negative value, PE and negative (three hole connectors are left) electricity
Pressure is positive value, and contrast circuit is shown in red by line sequence lamp, indicates that line sequence does not meet national standard.
4, comparison unit 4 is fetched from detection unit 3, to PE (on three hole connectors) and positive (three hole connectors are right), PE (three
On hole connector) it is calculated with negative (three hole connectors are left), positive (three hole connectors are right) with the voltage that (three hole connectors are left) detects is born
Comparison, when the difference that the actually detected voltage of positive electrode and negative electrode subtracts cathode voltage and PE is positive the half of grade and cathode measurement voltage
When (or positive and negative deviation is in 5V), socket detector anode suspension green light lights, and anode suspends red warning light if more than 5V
It is bright.When the actually detected voltage of positive electrode and negative electrode subtracts half of the difference of cathode voltage and PE for positive electrode and negative electrode measurement voltage
(or positive and negative deviation is in 5V), socket detector cathode suspension green light light, and the red warning light of cathode suspension is bright if more than 5V.
5, comparison unit 4 is fetched from detection unit 3, to PE (on three hole connectors) and positive (three hole connectors are right), PE (three
On hole connector) it is calculated with negative (three hole connectors are left), positive (three hole connectors are right) with the voltage that (three hole connectors are left) detects is born
Comparison compares the actually detected voltage phase adduction and the actually detected voltage of positive electrode and negative electrode of anode and PE, cathode and PE,
If difference is more than or equal to 3V, then it is determined as that ground path is bad, grounded signal lamp red light lights at this time, if difference is less than 3 volts
It is judged to being grounded normally, grounded signal lamp green light lights at this time.
Above specific embodiment is only the preferred embodiment of this creation, all in this wound not to limit this creation
Any modification, equivalent substitution, improvement and etc. done within the spirit and principle of work, should be included in this creation protection scope it
It is interior.
