Abstract
The utility model discloses a contact insertion depth measuring device for a trolley type circuit breaker. The trolley type circuit breaker is composed of more than one set of parallel contacts. Each set of contacts is composed of a moving contact 1 and a static contact 2, wherein the moving contact 1 is switched on after being inserted into the static contact 2. The movable contacts 2 are fixedly arranged on a movable trolley and the static contacts 2 are fixedly arranged on a cabinet. The device comprises more than one electroluminescent means. After each of all the electroluminescent means is connected in series with a power supply, the two ends of the electroluminescent means are respectively connected with the moving contact 1 and the static contact 2 of one set of contacts of the trolley type circuit breaker respectively. In this way, each set of contacts is correspondingly connected with one electroluminescent means and the electroluminescent means is in the form of a light emitting diode or a bulb. According to the technical scheme of the utility model, the traditional method of measuring the contact insertion depth for a trolley type circuit breaker is changed and the measurement accuracy is greatly improved. Meanwhile, the working efficiency is increased. The device is low in cost, safe, reliable, simple, easy and outstanding in technical effect.
Description
Technical field
The utility model relates to electric power apparatus examination field, is specifically a kind of for measuring the device of trolley type contact of breaker insertion depth.
Background technology
Trolley type isolating switch generally includes six groups of contacts, and each group contact comprises a moving contact and a static contact, and moving contact is arranged on the dolly that can slide along rectilinear orbit side by side, and static contact is arranged on switch cabinet.During use, promote dolly along rail moving, advance to working position, make moving contact insert conducting after static contact, and there is certain insertion depth.Fig. 1, Fig. 2 show the moving contact of wherein one group of contact of trolley type isolating switch and static contact disconnect and insert after situation, wherein 1 is moving contact, the 2nd, static contact.In actual applications, the degree of depth of inserting static contact as moving contact is inadequate, likely causes abnormal heating, causes device damage for trolley type isolating switch.Therefore,, in the work that trolley type isolating switch is overhauled, need to measure the insertion depth of contact.Traditional metering system is on contact, to smear vaseline, promotes dolly and withdraws behind working position again, then measures contact vestige and obtains insertion depth data, the measurement result out of true that this measuring method obtains.
Utility model content
The purpose of this utility model is to provide a kind ofly uses this device for measuring the device of trolley type contact of breaker insertion depth, can accurately measure the insertion depth of trolley type contact of breaker.
The technical solution of the utility model is as follows: a kind of for measuring the device of trolley type contact of breaker insertion depth, described trolley type isolating switch comprises one group of above contact arranged side by side, one group of contact comprises a moving contact 1 and a static contact 2, and moving contact 1 inserts the rear conducting of static contact 2; Moving contact 1 is fixed on movably on dolly, and static contact 2 is fixed on rack; Described device comprises an above electroluminescent device; After each electroluminescent device is connected with power supply, its two ends are connected respectively to moving contact 1 and the static contact 2 of one group of contact of described trolley type isolating switch; An electroluminescent device of each corresponding connection of group contact.Wherein, electroluminescent device is light emitting diode or bulb.
Principle of work of the present utility model is as shown in Figure 3: when moving contact does not also insert, choose a dolly slip reference position point in orbit
oas reference position.Fig. 3 cathetus
oGthe track that represents moving of car, arrow represents the direction of moving of car.Promoting dolly advances along rectilinear orbit, when the moving contact of a certain group of contact on dolly touches static contact, be connected on the loop conducting that power supply between moving contact and static contact and electroluminescent device form, electroluminescent device is lighted, and marks and lights the position of moment dolly as the initial turn-on position of this group contact.For example a point in Fig. 3, is the initial turn-on position of a group contact.Because trolley type isolating switch has been arranged side by side six groups of contacts conventionally, but the initial turn-on position of respectively organizing contact is not in one plane, so respectively organize contact, can and then contact successively conducting along with the front of dolly, and corresponding electroluminescent device is lighted successively; Mark one by one each electroluminescent device and light the position of moment dolly as the initial turn-on position of that group contact.As shown in Figure 3, b, c, d, e and f point are respectively the initial turn-on positions of b group, c group, d group, e group and f group contact; Finally promote again dolly and advance to working position point
gstop afterwards moving of car.Measure the initial turn-on position of a certain group of contact of trolley type isolating switch and the straight length between working position, be the insertion depth of this group contact.As Fig. 3 cathetus
aGlength, be exactly the insertion depth of a group contact.In order to measure conveniently, we also can measuring basis position and working position between straight length, deduct reference position and organize the straight length between contact initial turn-on position with certain, be the insertion depth of this group contact.As measure straight line
oGlength and
oalength,
oGdeduct
oalength equal
aGlength, be the insertion depth of a group contact.Other insertion depth of respectively organizing contact also measures as stated above.
The utility model has changed the measuring method of traditional trolley type contact of breaker insertion depth, has improved widely the precision of measuring, and has also promoted work efficiency simultaneously; Installation cost is cheap, safe and reliable, be simple and easy to use, has outstanding technique effect.

Embodiment
As Fig. 4, show for measuring the circuit theory diagrams of device of the trolley type contact of breaker insertion depth of six groups of contacts.Wherein, S1 is master switch, and R1 is dropping resistor, and after accumulator V2 and LED 1 series connection, two ends are connected respectively to moving contact and the static contact of the contact S2 of trolley type isolating switch.After S1 closure, when the moving contact of contact S2 has just contacted with static contact, the closed DC loop conducting of contact S2, LED1 is lit, and marks and lights the dolly position of moment as the initial turn-on position of this group contact.LED2-LED6 corresponds respectively to contact S3-S7.The present embodiment also provides charging circuit, and AC power V1 is that V2 charges by C1, R2 step-down by rectification circuit D1.
In above-mentioned embodiment, light emitting diode can also be replaced with to bulb, can reach equally the technique effect of expection.When electroluminescent device is selected bulb, power supply can be selected direct current or AC power.
