The existing generator outlet voltage transformer is arranged on a trolley type isolating switch, and after a cabinet door of a small voltage transformer cabinet is opened, the voltage transformer is directly exposed in front of an operator. When the voltage transformer needs to be pulled out or pushed into a trolley when power is cut off, an operator may touch the electrified part by mistake to cause electric shock. The utility model discloses the constitution includes: support base (7), baffle (2) and blocking device block tongue (5), the support base be fixed in voltage transformer cabinet body bottom, the support base with the one end of blocking device block tongue articulated, the other end of blocking device block tongue pass and fix the through-hole of the baffle bottom of voltage transformer cabinet body front end, the top of blocking device block tongue be fixed with blocking device stroke piece (3), the top protrusion of blocking device stroke piece insert in the bar hole at track (8) top. The utility model is used for voltage transformer dolly shutting.
Description
The technical field is as follows:
the utility model relates to a voltage transformer dolly blocking device.
Background art:
the outlets of the generators of the thermal power plant are respectively provided with a set of voltage transformer cabinet. Each voltage transformer is arranged on the trolley type isolating switch. After the cabinet door of the small voltage transformer cabinet is opened, the voltage transformer is directly exposed to an operator. When the voltage transformer needs to be pulled out or pushed into a trolley when power is cut off, an operator may touch the electrified part by mistake to cause electric shock.
The existing generator outlet voltage transformer is arranged on a trolley type isolating switch, and after a cabinet door of a small voltage transformer cabinet is opened, the voltage transformer is directly exposed in front of an operator. When the voltage transformer needs to be pulled out or pushed into a trolley when power is cut off, an operator may touch the electrified part by mistake to cause electric shock.
The utility model has the following contents:
the utility model aims at providing a voltage transformer dolly blocking device.
The above purpose is realized by the following technical scheme:
the utility model provides a voltage transformer dolly blocking device which constitutes including supporting base, baffle and blocking device block tongue, the support base be fixed in voltage transformer cabinet body bottom, the support base with the one end of blocking device block tongue articulated, the other end of blocking device block tongue pass and fix the through-hole of the baffle bottom of voltage transformer cabinet body front end, the top of blocking device block tongue be fixed with blocking device stroke piece, the top protrusion of blocking device stroke piece insert the strip downthehole at track top.
And a spring is connected between the locking device clamping tongue and the supporting base.
The voltage transformer trolley locking device is characterized in that the partition is an epoxy resin partition.
Has the beneficial effects that:
1. the utility model discloses front end horizontal longeron department installs the baffle additional and sets up blocking device in voltage transformer cubicle, eliminates the operator mistake and bumps electrified part and cause the risk of electric shock.
2. The utility model discloses a blocking device can carry on spacingly to voltage transformer dolly movement track, restricts the dismantlement of epoxy baffle simultaneously, guarantees operator's safety.
Description of the drawings:
FIG. 1 is a front view of the present invention;
fig. 2 is a top view of the present invention;
FIG. 3 is an enlarged view of portion A of FIG. 2;
FIG. 4 is an enlarged view of portion B of FIG. 1;
in the figure: 1. a voltage transformer trolley; 2. an epoxy resin separator; 3. a lockout device trip block; 4. an epoxy resin separator; 5. a locking device latch; 6. a spring; 7. a support base; 8. a track.
The specific implementation mode is as follows:
example 1:
the utility model provides a voltage transformer dolly blocking device, its constitution is including supporting base 7, baffle 2 and blocking device block tongue 5, support the base be fixed in voltage transformer cabinet body bottom, support the base with the one end of blocking device block tongue articulated, the other end of blocking device block tongue pass and fix the through-hole of the baffle bottom of voltage transformer cabinet body front end, the top of blocking device block tongue be fixed with blocking device stroke piece 3, the top protrusion of blocking device stroke piece insert the bar downthehole at track 8 tops.
Example 2:
according to the voltage transformer trolley locking device in the embodiment 1, a spring 6 is connected between the locking device clamping tongue and the supporting base.
Example 3:
the voltage transformer trolley locking device according to embodiment 1 or 2, wherein the partition is an epoxy partition.
The working principle is as follows: a partition plate is additionally arranged at a transverse longitudinal beam at the front end in the small voltage transformer cabinet, and a locking device is arranged. The partition board is made of an epoxy resin board and is fixed at the front end transverse and longitudinal beam in the small voltage transformer cabinet through bolts. The locking device adopts a mechanical locking form, so that when the voltage transformer trolley is electrified at the working position, the locking device is in a locking state, and the locking device clamping tongue is positioned in the through hole of the partition plate and hooks the partition plate, so that the partition plate cannot be detached. When the voltage transformer cabinet is overhauled, the voltage transformer trolley needs to be shaken out firstly, so that the voltage transformer has power failure, the voltage transformer trolley travels to an overhauling position, the wheel of the trolley presses the protruding part at the top of the stroke block of the locking device, the locking device clamping tongue rotates, the locking function is removed, the partition plate can be detached at the moment, and then the voltage transformer cabinet is overhauled. When the maintenance is finished and the voltage transformer needs to be powered on, the partition plate needs to be installed at a specified position and then the partition plate is shaken into the voltage transformer trolley. And after the voltage transformer trolley leaves the overhaul position, the locking device is locked again.
