Description
Technical Field
The utility model belongs to colliery electromechanical field especially relates to a move and become high pressure side isolator with divide disconnected degree to detect.
Background
The high-voltage side isolating switch of the underground explosion-proof mobile substation is a component with higher failure rate, the analysis reason is basically caused by the fact that the switch-on is not in place, although the upper cavity of the high-voltage side vacuum switch is provided with an observation hole, whether the high-voltage isolating switch is completely switched on or not can not be clearly and comprehensively observed under the limitation of a light source, the contact degree of a moving contact and a static contact of the high-voltage isolating switch is not detected by a detection device and is judged by the moving sense of manpower, so when the contact area of the moving contact and the static contact is smaller, the current born by the high-voltage side isolating switch is very large, and the contact is overheated, and even the arc-drawing short circuit, the phase.
Disclosure of Invention
An object of the utility model is to provide a move and become high-pressure side isolator with divide disconnected degree to detect, this switch fault rate is low, safe and reliable.
In order to achieve the above purpose, the technical scheme of the utility model: a shift-transformer high-voltage side isolating switch with breaking degree detection comprises a shift-transformer high-voltage side isolating switch, wherein an observation port is formed in the top surface of a flame-proof box of the shift-transformer high-voltage side isolating switch, a plurality of binding posts are installed on a bottom plate, a plurality of disconnecting links are installed on a rear plate of the flame-proof box corresponding to the binding posts, a shaft lever is installed on the upper portion of the rear plate of the flame-proof box through a bearing seat, one end of the shaft lever extends out of the flame-proof box, an operating handle is installed at the end of the shaft lever, a plurality of connecting rods are hinged to the shaft lever, the other,
still include power module, LED lamp, disconnected detection mechanism, the LED lamp is installed in flame proof box top surface bottom, LED lamp and power module line connection, disconnected detection mechanism, including travel switch, driving lever, the driving lever includes sleeve, fixed connection's driving lever on the sleeve, be provided with the fixed orifices on the sleeve, be provided with fixing bolt on the fixed orifices, sleeve suit is at the inner head of axostylus axostyle case, travel switch installs on the backplate, is located the driving lever downside, cooperates with the driving lever, travel switch establishes ties on 100V control loop.
And the control switch of the LED lamp is a normally open contact of a locking button of a shift high-voltage side isolating switch.
When the stroke switch is closed, the shaft lever rotates to enable the contact area of the moving contact of the disconnecting link and the fixed contact of the binding post to reach 75%.
The utility model discloses simple structure, convenient to use utilizes LED to supply light and is convenient for the workman to observe the degree of contact of switch moving contact and terminal static contact, utilizes driving lever and travel switch's cooperation simultaneously, guarantees the degree of contact of switch to effectively avoid causing contact overheated, isolator arc-discharge short circuit, lack the looks or burn out the accident.

Detailed Description
As shown in figures 1 and 2 of the drawings,
a shift-transformer high-voltage side isolating switch with breaking degree detection comprises a shift-transformer high-voltage side isolating switch, wherein an observation port is formed in the top surface of a flame-proof box of the shift-transformer high-voltage side isolating switch, three binding posts 11 are installed on a bottom plate, three disconnecting links 12 are installed on a rear plate of the flame-proof box and correspond to the binding posts, a shaft rod 13 is installed on the upper portion of the rear plate of the flame-proof box through a bearing seat, one end of the shaft rod 13 extends out of the flame-proof box, an operating handle 14 is installed at the end, a plurality of connecting rods 15 are hinged on the shaft rod 13, the other end of each connecting rod 15,
still include power module 2, LED lamp 3, divide disconnected detection mechanism, LED lamp 3 is installed in flame proof case top surface bottom, the LED lamp with install the power module line connection in the isolator box, divide disconnected detection mechanism, including travel switch 4, the driving lever includes sleeve 51, fixed connection is driving lever 52 on the sleeve, be provided with the fixed orifices on the sleeve, be provided with fixing bolt 53 on the fixed orifices, the sleeve suit is at the inner tip of axostylus axostyle case, travel switch 4 installs on the backplate, be located the driving lever downside, with the driving lever cooperation, travel switch establishes ties on 100V control loop, when the travel switch closed, the axostylus axostyle rotation makes the switch moving contact and terminal static contact area reach 75%.
The control switch of the LED lamp is a normally open contact of a locking button of a shift high-voltage side isolating switch.
When the moving-changing high-voltage vacuum switch is used, the handle is rotated, the rotating shaft drives the connecting rod to push the moving contact of the disconnecting link to be in contact with the fixed contact of the binding post, and when the contact area of the moving contact and the fixed contact reaches 75% of the coal mine safety management regulation, the deflector rod pushes the operating head of the travel switch to drive the normally open contact to be closed, the 100V control loop is conducted, and then the moving-changing high-voltage vacuum switch can be operated on the next step.
