(3) when carrying out separating brake or closing operation to double-column horizontal rotation type disconnecting switch every time, the rotation band of support insulator Dynamic No. 1 group and No. 2 group rotations;When combined floodgate, the infrared launcher of fingertip lateral brace No. 2 groups of insulator is with support insulator up time Needle is rotated by 90 ° counterclockwise, and the infrared receiving device of contact lateral brace No. 2 groups of insulator is also counterclockwise or suitable with post insulator Hour hands are rotated by 90 °, issue with finish receiving dock when and be complete combined floodgate within the scope of allowable error;Direction of rotation when separating brake On the contrary, issue with finish receiving dock when and be complete separating brake within the scope of allowable error;
(4) when double-column horizontal rotation type disconnecting switch is able to achieve complete separating brake at the appointed time or closes a floodgate completely, corresponding 1 Number group and No. 2 groups issue complete divide-shut brake electric signals;If after a certain period of time, No. 1 group and the still not sent complete divide-shut brake electricity of No. 2 groups Signal, then it represents that disconnecting switch is in half point or hemizygous condition, and controller issues corresponding incomplete divide-shut brake electric signal at this time;
(5) after the completion of each divide-shut brake, the completion status of movement is sent to control by No. 1 group and No. 2 groups as electronic signals The indoor controller with display is made to be shown.
Preferably, in the controller built-in double-column horizontal rotation type disconnecting switch divide-shut brake graphic package;Work as control When device processed receives complete divide-shut brake or not complete opening and closing state value, different divide-shut brake animations is presented in display screen.
Preferably, in the step (4), it is 12 seconds that disconnecting switch, which is in half point or the judgement time of hemizygous condition,.
Compared with prior art, the present invention has the advantage that
The present invention can real-time monitoring double-column horizontal rotation type disconnecting switch divide-shut brake in place the case where, staff can to every The divide-shut brake for leaving pass carries out a distant place (monitoring room) monitoring, can monitor the whether complete divide-shut brake of disconnecting switch, energy in the distance In place whether timely detection and isolation switch division, improve the accuracy rate of monitoring, and can reduce the risk that artificial scene is checked, save It makes an appointment, moreover it is possible to avoid because of the erroneous judgement that the height of personnel's level of skill occurs.
Specific embodiment
The following is a clear and complete description of the technical scheme in the embodiments of the invention, and those skilled in the art will Understand, the following example is merely to illustrate the present invention, and should not be taken as limiting the scope of the invention.It is not specified in embodiment specific Technology or conditions person described technology or conditions or carries out according to the literature in the art according to product description.It is used Production firm person is not specified in reagent or instrument, is the conventional products that can be obtained by purchase.Obviously, described embodiment Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field Art personnel every other embodiment obtained under that premise of not paying creative labor belongs to the model that the present invention protects It encloses.
Near real-time quantitative monitoring method, this method include in following in place for a kind of double-column horizontal rotation type disconnecting switch divide-shut brake Hold:
(1) it when double-column horizontal rotation type disconnecting switch is in complete separating brake, is installed in each phase fingertip lateral brace insulator bottom One infrared transmitting device installs one and infrared transmitting device pairing in the bottom of each phase contact lateral brace insulator Infrared receiver, infrared transmitting device and infrared receiver are in complete mated condition and according to each producer's twin columns Equipment error range, this group of infrared transmitting device and infrared receiver is arranged in horizontal rotation type isolation switch technical requirements For detecting complete separating brake, it is defined as No. 1 group;
