Description
Technical field
The invention belongs to high voltage electrical apparatus technical field, relate to the clamping force measurement mechanism of a kind of scissor disconnector, clamp type disconnector.
Background technology
Due to developing rapidly of present State Grid cause, disconnector output increases considerably, original clamping force measurement mechanism can not meet measurement requirement, but in high-voltage alternating current isolating switch actual motion, must ensure that dynamic/static contact contacts reliably, this just requires that moving contact has enough large acting force to static contact, and this acting force is the important indicator weighing dynamic/static contact reliable contacts.According to the requirement of user and design, the size of this power must be out tested before product export, reaches the requirement of properties of product.At present, scissor disconnector, clamp try the disconnector conventional device for testing clamping force between general structure factors such as all more complicated, measuring accuracy are not, reliability is not high, operation is not convenient.Such as, existing Authorization Notice No. is the Chinese patent that the name of CN101710010B is called " device for testing clamping force between moving contact and fixed contact of isolating switch ", disclose a kind of disconnector sound and lift one's head device for testing clamping force between, this measurement device process more complicated, operation inconvenience, measurement efficiency is low, and this is disconnector clamping force measurement mechanism urgent problem.
Summary of the invention
The object of this invention is to provide a kind of disconnector clamping force measurement mechanism, to solve clamping force measurement mechanism measuring process more complicated, operation inconvenience, to measure inefficient problem.
For achieving the above object, the solution of the present invention is: a kind of disconnector clamping force measurement mechanism, comprise the first press section and the second press section, each press section is xsect cylinder arcuately, the bowstring part of two press sections is oppositely arranged, between be provided with pressure transducer, two force sides of this pressure transducer are fixedly connected with the first press section, the second press section respectively, and the signal output part of this pressure transducer is connected with pressure display unit.
Pressure transducer and the first press section, the second press section is set firmly by screw.
Described first press section two ends are provided with the limited block that spacing second press section moves axially along the first press section.
Disconnector clamping force measurement mechanism of the present invention in use, when disconnector closes a floodgate, both sides moving contact produces to two press sections that a pair size is identical, direction opposite effect power simultaneously, this acting force is passed on the pressure transducer that is connected with two press sections, numerical value is passed to pressure display unit to show pressure value in real time by data line by pressure transducer, installation or testing staff just according to the force value of display, can adjust corresponding adjusting gear, and then are met the clamping force of designing requirement.Apparatus structure of the present invention is simple, reliability is high, makes user of service directly can read force value by display, facilitates operation, improve measurement Efficiency and accuracy.Two press sections are linked together by pressure transducer, its outer peripheral face basic comprising face of cylinder, for simulating a static contact profile, static contact is extruded closer to truth lower moving contact like this when both sides moving contact applies pressure to two press sections, also can pressure transducer uniform force, improve measuring accuracy.

Embodiment
Be using state figure as shown in Figure 3,4, two moving contacts 5 of scissor disconnector clamp, and clamp the clamping force measurement mechanism 6, clamping force F of the present embodiment as shown in Figure 4.The stressed sensing part of clamping force measurement mechanism simulates the profile of static contact---and overall in column type, the stressed sensing part of clamping force measurement mechanism is made up of two parts, as Fig. 2, first press section 2 and the second press section 3, first press section and the second press section are all xsects is arc cylinder, bowstring part be corresponding plane, between pressure transducer 1 is set, pressure transducer connects display.Two press sections are combined, and the outer peripheral face of back of a bow part synthesizes column type substantially.
With GW46 series scissor high-voltage alternating current isolating switch moving contact clamping force be measured as example, when high-voltage alternating current isolating switch closes a floodgate, it is identical that both sides moving contact 5 produces a pair size to the first press section and the second press section simultaneously, direction opposite effect power, this acting force has passed to coupled pressure transducer, force value is passed to coupled pressure display unit by data line by pressure transducer, pressure display unit in real time by force value display on a display screen, installation or testing staff just can according to the force value of display, adjust corresponding adjusting gear, and then be met the clamping force of designing requirement.
As a kind of embodiment, as shown in Figure 1 and Figure 2, the two ends, left and right between two press sections are fixed with pressure transducer 1 respectively, and the signal output part of pressure transducer 1 is connected with the pressure display unit 4 that can show force value.Pore in Fig. 2 represents the attachment screw 9 of pressure transducer 1 and the first press section 2.
Being the structural representation of the first press section as shown in Figure 6,7, is the structural representation of the second press section as shown in Figure 8,9.
As shown in Figure 5, in figure the connection of the first press section 2 and the second press section 3 be exactly web member joint by pressure transducer carries with and threaded hole.Assembly method first sensor is fixed on the first extruder member 2, and then with screw, the second extruder member 3 is fixed on pressure transducer 4 other end.
The outer peripheral face of the first press section and the second press section forms a circumference, so just, simulate static contact profile, like this when both sides moving contact applies pressure to two press sections closer to truth lower moving contact extruding static contact, also can pressure transducer uniform force, improve measuring accuracy.
In order to not in extrusion process because longitudinal force makes to occur relative sliding between the first press section and the second press section, position limiting structure can be set between two press sections.As shown in Figure 6, the first press section two ends are provided with limited block 8 towards the second press section direction, stop moving axially of relative first press section of the second press section.
