Description
Technical field
This utility model provides marine electrical equipment debugging facility, AC socket the most peculiar to vessel test device.
Background technology
Exchange 230V socket peculiar to vessel is to use panel on ship to power, and its characteristics of power supply is two phase firewires, a phase ground wire.The two each phases of phase firewire are all with the most about 115V alternating voltage, and ground wire is connected as protection against electric shock ground protection with hull.Traditional testing tool is digital multimeter, during test voltage, needs circuit tester to get to voltage gear, tests two phase firewires with two test pencils simultaneously and determine power-on voltage;During test ground protection, needing circuit tester to get to resistance grade, access ground wire jack to be measured with a test pencil, another test pencil finds the earth point on hull, to determine that between ground wire jack to be measured and hull earth point, resistance is zero.Use circuit tester to test each socket, not only need ceaselessly to convert the gear of ammeter, in addition it is also necessary to finding good hull earth point, operation complexity, workload is big.
Summary of the invention
Complicated in order to solve exchange 230V socket test process peculiar to vessel, the problem needing hull earth point, this utility model provides AC socket peculiar to vessel test device.This device passes through being connected with each other of main control box, testing button and display lamp, solves the technical problem of socket for ship on-state test.
This utility model solves the scheme of technical problem employing:
220V AC power cord is connected to power supply indicator and misphase display lamp, connect at earth terminal and have grounded signal lamp, power supply indicator, misphase display lamp and grounded signal lamp are separately mounted on main control box, being also equipped with testing button on Main Control Tank, socket for ship matched plug is connected with main control box with power line by three-core cable butt joint.
Good effect, this utility model shows duty and the switching performance of socket by display lamp, has advantage easy to use.Suitably as exchange 230V socket peculiar to vessel test device application.
Accompanying drawing explanation
Fig. 1 is this utility model structure member figure
Fig. 2 is this utility model circuit theory diagrams
In figure, 1. socket for ship matched plug, 2. three-core cable butt joint, 3. power line, 4. main control box, 5. power supply indicator, 6. grounded signal lamp, 7. misphase display lamp, 8. testing button.
Detailed description of the invention:
According to the figure, 220V AC power cord is connected to power supply indicator 5 and misphase display lamp 7, connect at earth terminal and have grounded signal lamp 6, power supply indicator, misphase display lamp and grounded signal lamp are separately mounted on main control box 4, being also equipped with testing button 8 on Main Control Tank, socket for ship matched plug 1 is connected with main control box with power line 3 by three-core cable butt joint 2.
Described power supply indicator is white, grounded signal lamp is red zone buzzer for green, misphase display lamp.
This utility model use process:
1, select to exchange, with peculiar to vessel, the plug that 230V socket is supporting, be connected with power line by general three-core cable butt joint.
2, matched plug is inserted exchange 230V socket peculiar to vessel to be measured, by socket for ship power transmission to be measured.
3, according to power supply indicator, grounded signal lamp, the light on and off state observation measurement condition of misphase display lamp:
A. bright when power supply indicator, grounded signal lamp and misphase display lamp do not work, and after pressing testing button, if grounded signal lamp lights, then explanation occurs without disconnected phase, misphase, and socket is powered normally, and ground protection function is normal;
B. bright when power supply indicator, grounded signal lamp and misphase display lamp do not work, and after pressing testing button, if grounded signal lamp, misphase display lamp still do not work, then explanation socket is powered normally, but earth lead loose contact, ground protection disabler;
C. not working when power supply indicator, grounded signal lamp and misphase display lamp do not work yet, and press testing button, if grounded signal lamp lights, then a phase power line loose contact in explanation two-phase power supply jack, power supply breaks phase, but ground protection function is normal;
D. not working when power supply indicator, grounded signal lamp and misphase display lamp do not work yet, and press testing button, if power supply indicator, grounded signal lamp and misphase display lamp still do not work, then at least one phase power line loose contact are described, ground protection function is undetermined.
E. not working when power supply indicator, misphase display lamp is bright, and grounded signal lamp does not works, and after pressing testing button, grounded signal lamp lights, then in the power line on explanation socket, a phase and ground line connects instead, ground protection disabler.
4, according to different test results, after socket power-off, malfunction elimination is carried out.
5, repeat 2,3 steps, test when 3a operating mode occurs and terminate.
This utility model principle and feature:
Operation principle: this device mainly by power supply peculiar to vessel each phase of two-phase power supply all with the most about exchange 115V voltage feature: selection work voltage be exchange 190V ~ 240V white indicating light, as power supply indicator, the only all wiring of two phase firewires and the function of socket for ship is normal, and this display lamp just can light;Selection work voltage be the red led of band buzzer of exchange 90V ~ 175V be misphase display lamp, this display lamp is only accessing a phase firewire and ground wire, the situation of voltage about 115V, just can light buzzer simultaneously and sound, play the effect of misphase instruction;Selection work voltage be exchange 90V ~ 120V green indicating lamp be grounded signal lamp, when this display lamp accesses a phase firewire and ground wire, during voltage about 115V, this display lamp lights.Add relay and testing button in systems, play the effect of function locking and test.
Feature of the present utility model:
This device be furnished with can the test plug of plug and pull, a socket only need to once plug, it is not necessary to finding external hull earth point, simple to operation, a people is the most operable, and test result shows according to display lamp, very clear.This device volume is little, be easy to carry, practical.
