Description
Technical field
The utility model relates to the vacuum circuit breaker pick-up unit, and the vacuum circuit breaker pick-up unit especially under the coal mine is specially a kind of vacuum circuit breaker synchronous detecting instrument.
Background technology
Present antiknock device evacuation gradually under industrial and mining enterprises, the particularly coal mine, the vacuum circuit breaker of high and low voltage switch is when maintenance, and the inspection in three-phase gap is judged very inconvenient with multimeter, and inaccurate; Because multimeter can only detect single-phase break-make, can't detect the synchronism of three-phase closure, whether promptly can't detect the three-phase gap consistent.Other synchronous detection machine must have external power supply, not explosion-proofly easily causes gas explosion, and the big operation of volume is extremely inconvenient, is not suitable under the coal mine.
Summary of the invention
The utility model detects vacuum circuit breaker three-phase gap inconvenience and inaccurate in order to solve with multimeter, and other synchronous detection machine is not suitable for the problem under the coal mine, and a kind of vacuum circuit breaker synchronous detecting instrument is provided.This vacuum circuit breaker synchronous detecting instrument is the little portable sensitive reliable detection instrument that does not produce electric spark in light weight of a kind of volume, is particularly useful under the coal mine.
The utility model is to adopt following technical scheme to realize: vacuum circuit breaker synchronous detecting instrument, comprise the testing circuit in housing and the housing, testing circuit comprises battery, be connected in series and place the switch on the case panel with battery, three are connected in series the branch road that forms successively by resistance, light emitting diode and jack, resistance one end of three branch roads links to each other with the positive pole of battery through switch, and light emitting diode and jack in three branch roads are arranged on the case panel; Also comprise an independent jack (i.e. another jack beyond three jacks in three branch roads), an end of independent jack links to each other with battery cathode and is arranged on the case panel; Comprise that again three one ends are that plug, the other end are that detection line and one one end of wire clamp is the three fork detection lines that plug, the other end have three wire clamps.During use, the plug of three detection lines is inserted respectively in three jacks on the case panel, in the independent jack on the plug insertion case panel of three fork detection lines, the wire clamp of three detection lines is clipped in respectively on the lead on three-phase vacuum tube top, three wire clamps of three fork detection lines are clipped in respectively on the lead of three-phase vacuum tube bottom, and the power switch on the closure shell panel manually closes a floodgate then gradually, three light emitting diodes are simultaneously bright, illustrate that the vacuum tube contact is good and synchronous.Do not work if any a light emitting diode, illustrate that this vacuum tube does not contact.If light emitting diode is early bright or bright late, illustrate asynchronous, the need adjusting play.
Whether the break-make that can detect vacuum circuit breaker synchronous detecting instrument described in the utility model can detect synchronous again, has in light weightly, and volume is little, and is portable, uses easy to operately, sensitive reliable, does not produce electricity and cremates characteristics such as safety anti-explosive.Be applicable to particularly gassy mine of industrial and mining enterprises.
