Description

Reduce temperature rise type copper-manganese sampler
Technical field
The utility model is related to a kind of electric energy meter, more particularly, to a kind of reduction temperature rise type for being easy to radiate in electric energy meter Copper-manganese sampler.
Background technology
In electric power network technique code requirement, clearly propose Intelligent current table need with neutral line current measure, record Function, and have strict error requirements.In Intelligent current table zero line loop current transformer is sealed in be sampled, such as it is entitled The electric energy meter of on-line measurement residual current " a kind of can "(Publication number CN204228778U), entitled " a kind of intelligent electric energy meter "( Publication number CN202903839U)Public technology be such a application, but the existing skill including above-mentioned two public technology Art, fast, often higher in the temperature state of sampler temperature rise speed.
The content of the invention
The utility model main purpose is to provide a kind of slower reduction temperature rise type copper-manganese sampler of temperature rise speed.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals:Reduce temperature rise type manganese Copper sampler, it includes sampler body, and sampler body is plate body structure, is had:As the radiating surface in heat transferring contact face, For planar structure;Inner fovea part, positioned at the middle side part of radiating surface one;Connecting portion, in inner fovea part both sides, respectively with two binding posts Connection;Several joints, are arranged on sampler this body sidewall, and one of joint is located in the inner fovea part.Carrying is more Heat, can slow down temperature rise speed;With larger heat-conducting area, heat conductivility is improved, it is to avoid heat is difficult to diffuse to form heat It is collected in part.
Preferably, the joint is the projection that sampler this body sidewall stretches out.This structure, raised and sampler Body formation integrative-structure.
Preferably, described raised in bar shaped, the raised head of two of which is bent in hooking again, and hook part and place side wall are big Body is parallel.It is easy to wiring, increases the wire connecting portion distance of adjacent joint.
Preferably, the sampler body has the through hole that may pass through cable, through hole is located in the middle part of radiating surface.Cable is just It is difficult for drop-off in fixation.
Preferably, the joint head bending in inner fovea part, bending g. slice header points to the middle part of inner fovea part and not across interior In the middle part of recess.Improve the convenience of patching operations.
Therefore, the utility model has the advantages that.
1st, using the sampler body of plate body structure, it is possible to provide larger volume is to carry more heats, it is to avoid short-term Inside it is rapidly heated.
2nd, using the radiating surface of planar structure, it is possible to provide larger contact area, it is easy to and external heat transfer, with higher Heat transference efficiency, further slow down temperature rise speed.
3rd, using the structure of inner fovea part and connecting portion, assembling, wiring facilitate.
4th, connecting portion and sampler body are structure as a whole, and structural strength is big, with good electrical efficiency.
5th, by the through hole that may pass through cable in the middle part of radiating surface, with connecing for the head bending in inner fovea part Head, fixes wiring more convenient, more firm, difficult for drop-off.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment:The utility model reduces temperature rise type copper-manganese sampler, and as shown in Figure 1, it includes sampler body 8, Sampler body 8 is plate body structure, is had:It is planar structure, it is possible to provide larger as the radiating surface 87 in heat transferring contact face Contact area is easy to and external heat transfer, may also provide larger volume to carry more heats, it is to avoid quick in a short time to rise Temperature;Inner fovea part 85, positioned at the middle side part of radiating surface 87 1, is easy to middle part to avoid interference, the connecting portion 86 of both sides is stretched to terminal On be fixedly connected;Connecting portion 86, in the both sides of inner fovea part 85, is connected with two binding posts 7 respectively;Three joints 81,82, 84, the side wall of sampler body 8 is arranged on, one of joint is located in inner fovea part 85.
Joint 81,82,84 is the projection that the side wall of sampler body 8 stretches out.It is raised to be integrated knot with sampler body Structure, intensity is big, and electric conductivity is good.
Projection is in bar shaped, and the raised head of two of which is bent in hook, hook part and place side wall general parallel orientation again.It is easy to connect Line, and increase wiring weld part or the distance with adjacent wiring.
Sampler body 8 has the through hole 83 that may pass through cable, and through hole 83 is located at the middle part of radiating surface 87.In inner fovea part 85 Joint head is bent, and bending g. slice header points to the middle part of inner fovea part 85 and not across the middle part of inner fovea part 85.Cable is passed from through hole 83 Go out, delivered to along radiating surface in inner fovea part 85, bend insertion bending g. slice header again in inner fovea part 85.
Set in the utility model, on the bottom surface 2 of drain pan 1 on stage body 5, stage body 5 and several binding posts 6 are set, each Binding post 6 connects a binding post 7, and two of which binding post 7 is zero line into and out of terminal;Two adjacent binding posts 7 It is connected with sampler 8;The body of sampler 8 is the smooth plate body in upper surface, a middle side part indent, and depressed part both sides are and wiring The connecting portion 85 that terminal 7 connects.The frame of the connection drain pan 1 of stage body 5 bottom, and second step 4 is formed to the extension of the middle part of drain pan 1, Second step 4 forms first step 3 to extension in the middle of housing, and the top surface of second step 4 is higher than the top surface of first step 3, wiring Terminal 7 is passed from second step 4 to the top of first step 3.
