Abstract
The utility model discloses a kind of secondary nuclear phase assisting device of hand-held, including, hand-held fixed tray, universal meter and four selection switches.When carrying out nuclear phase work, A, B, C, N phase voltage of benchmark screen cabinet are introduced to the movable terminal of four selection switches, the voltage input end wherein one end for being switched to a certain phase reference voltage currently needed by change-over switch and accessing multimeter, the other end of the voltage input of multimeter accesses in the voltage circuit of screen cabinet to be detected, carries out nuclear phase.The utility model can promote the efficiency of nuclear phase, while avoid operating due to caused by confusing communication when double nuclear phase asynchronous with actual requirement.
Description
Technical field
The utility model patent disclose it is a kind of it is practical and efficient, avoid manually linking up or operation error carries out indoor inspection
The secondary nuclear phase assisting device of hand-held.
Background technique
Nuclear phase is based substantially on 2 people to 3 people to cooperate to complete at present, and a people is in benchmark screen cabinet, and a people is in screen to be tested
Cabinet, another person keep a record (be also likely to be that people of screen cabinet to be tested keeps a record, if 3 people, the meeting to keep a record and to be tested
Shield the people of cabinet together).Wherein in the people of benchmark screen according to the requirement of recorder, replace each phase of ABCN, be usually propaganda directed to communicate or
Intercom, since noise is very big in power plant, it is asynchronous with actual requirement to be possible to will appear operation in communication, while benchmark
The personnel of screen are thread-changing, waiting, continue thread-changing, and Comparision is single.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the disadvantages mentioned above of the prior art, provides a kind of hand-held
Secondary nuclear phase assisting device.
In order to solve the above technical problems, the secondary nuclear phase assisting device of a kind of hand-held provided by the utility model, comprising:
Universal meter and multidigit switching switch, the multidigit switching switch has a fixing terminal and four selection terminals, and is used for
The knob of route choosing, the fixing terminal are connected with the conducting wire A for connecting with universal meter measurement hole location, conducting wire A's
Free end is fixed with the plug for being suitably inserted into universal meter measurement hole location, and each selection terminal of the multidigit switching switch is respectively
Be connected with the conducting wire for connecting with benchmark screen cabinet corresponding wiring terminal, described device also have a both ends be respectively used to
The conducting wire B that test panel cabinet connecting terminal is connected with universal meter measurement hole location.
The secondary nuclear phase assisting device top of the utility model hand-held is the module of fixed multimeter, and lower part is a switching
Switch.When carrying out nuclear phase work, A, B, C, N phase voltage of benchmark screen cabinet are introduced to the movable terminal of four selection switches, passed through
Voltage input end wherein one end that change-over switch is switched to a certain phase reference voltage currently needed and accesses multimeter, multimeter
The other end of voltage input access in the voltage circuit of screen cabinet to be detected, carry out nuclear phase.
The utility model can promote the efficiency of nuclear phase, while the operation due to caused by confusing communication when avoiding double nuclear phase
It is asynchronous with actual requirement.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the secondary nuclear phase assisting device circuit diagram of the utility model hand-held.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of secondary nuclear phase assisting device of hand-held of the present embodiment, there is a hand-held fixed tray, ten thousand
The top of pallet is fixed on ammeter, four switching switches are fixed on the lower part of pallet, and four switching switches have a fixing end
Son and four selection terminals, and the knob for route choosing.Fixing terminal is connected with for measuring hole location with universal meter
The conducting wire A of connection, the free end of conducting wire A are fixed with the plug for being suitably inserted into universal meter measurement hole location.Four switching switches
Four selection terminals be connected with the A phase voltage terminal, B phase voltage terminal, C phase voltage terminal, N being respectively used to benchmark screen cabinet
The conducting wire that phase voltage terminal is connected.Also there are device a both ends to be respectively used to and screen cabinet connecting terminal to be tested and general-purpose electricity
Table measures the conducting wire B of hole location connection.
In this example, the free end of conducting wire A is fixed with the plug for being suitably inserted into universal meter measurement hole location；Conducting wire B and general-purpose
One end of ammeter measurement hole location connection is fixed with the plug for being suitably inserted into universal meter measurement hole location.
When carrying out nuclear phase work, A, B, C, N phase voltage of benchmark screen cabinet are introduced to the movable terminal of four selection switches, surveyed
When examination personnel wish which benchmark screen cabinet takes mutually be used as a reference source, manual switching once selects switch, can save in this way
One people, while demand caused by communication problem and practical inconsistent will not be caused by, cause test result incorrect and
Repeatedly test, or itself it is wrong simultaneously because benchmark screen lead-in mistake, finally give correct result seemingly.
In addition to the implementation, the utility model can also have other embodiments.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
